Cisco IOS XR Software running on the Cisco CRS Router provides the following features and benefits:
- IP and Routing—This supports a wide range of IPv4 and IPv6 services and routing protocols such as Border Gateway Protocol (BGP), Routing Information Protocol (RIPv2), Intermediate System-to-Intermediate System (IS-IS), Open Shortest Path First (OSPF), IP Multicast, Routing Policy Language (RPL), Hot Standby Router Protocol (HSRP), and Virtual Router Redundancy Protocol (VRRP) features.
- BGP Prefix Independent Convergence—This provides the ability to converge BGP routes within sub seconds instead of multiple seconds. The Forwarding Information Base (FIB) is updated, independent of a prefix, to converge multiple 100K BGP routes with the occurrence of a single failure. This convergence is applicable to both core and edge failures and with or without MPLS. This fast convergence innovation is unique to Cisco IOS XR Software.
- Multiprotocol Label Switching (MPLS)—This supports MPLS protocols, including Traffic Engineering (TE), Resource Reservation Protocol (RSVP), Label Distribution Protocol (LDP), Virtual Private LAN Service (VPLS), Layer 2 Virtual Private Network (L2VPN), and Layer 3 Virtual Private Network (L3VPN).
- Multicast—This provides comprehensive IP Multicast software including Source Specific Multicast (SSM) and Protocol Independent Multicast (PIM) in Sparse Mode only, and Bidirectional Protocol Independent Multicast (BIDIR-PIM).
- Quality of Service (QoS)—This supports QoS mechanisms including policing, marking, queuing, random and hard traffic dropping, and shaping. Additionally, Cisco IOS XR Software also supports modular QoS command-line interface (MQC). MQC is used to configure QoS features.
- Manageability—This provides industry-standard management interfaces including modular command-line interface (CLI), Simple Network Management Protocol (SNMP), and native Extensible Markup Language (XML) interfaces. Includes a comprehensive set of Syslog messages.
- Security—This provides comprehensive network security features including access control lists (ACLs); routing authentications; Authentication, Authorization, and Accounting (AAA)/Terminal Access Controller Access Control System (TACACS+), Secure Shell (SSH), Management Plane Protection (MPP) for management plane security, and Simple Network Management Protocol version3 (SNMPv3). Control plane protections integrated into line card Application-Specific Integrated Circuits (ASICs) include Generalized TTL Security Mechanism (GTSM), RFC 3682, and Dynamic Control Plane Protection (DCPP).
- Availability—This supports rich availability features such as fault containment, fault tolerance, fast switchover, link aggregation, nonstop routing for ISIS, LDP, BGP, and OSPF, and nonstop forwarding (NSF).
- Multicast service delivery in SP NGN—MVPNv4 support carries multicast traffic over an ISP MPLS core network.
- IPv6 Provider Edge Router support for IPv6 applications—This delivers IPv6 traffic over an IPv4/MPLS core with IPv6 provider edge router (6PE) support.
- IPv6 VPN over MPLS (6VPE) support—This delivers IPv6 VPN over MPLS (IPv6) VPN traffic over an IPv4 or MPLS core with 6VPE support.
- IPv6 VPN over IP —This delivers IPv6 VPN over IP traffic.
NoteIPv6 VPN over MPLS and IPv6 VPN over IP won't co-exist
- Carrier Grade Network Address Translation (CGN)—This enables services providers to execute orderly transitions to IPv6 through mixed IPv4 and IPv6 networks. CGN provides address family translation but is not limited to just translation within one address family. CGN delivers a comprehensive solution suite for IP address management and IPv6 transition.
- Enhanced core competencies:
- IP fast convergence with Fast reroute (FRR) support for intermediate System-to-Intermediate System (IS-IS) and OSPF
- Traffic engineering support for unequal load balancing
- Traffic engineering over generic routing encapsulation (GRE) tunnel interfaces—LDP, L2VPN, and L3VPN over TE over GRE are supported. VPN routes over TE and over GRE, require a labelled path for path resolution
- VRF support for GRE tunnel interfaces—This support includes GRE tunnel interfaces under a VRF, however the GRE tunnel source and destination are in the global table
- RSVP support over GRE tunnels
- Path Computation Element (PCE) capability for traffic engineering

Software Features Introduced in Cisco IOS XR Software Release 4.3.1
BFD IPv6 Multihop
Bidirectional Forwarding Detection (BFD) Multihop IPv6 (MHv6) feature supports BFD sessions between interfaces that are multiple hops away. The BFD MHv6 enables a BFD session between two addresses (BFD session between provider edge (PE) and customer edge (CE) loopback addresses or BFD session between routers that are several time-to-live (TTL) hops away) that are not on the same interface. BFD MHv6 is supported in a typical CE – PE (CRS) configuration over loopback as well as the physical interface addresses, with static IPv6 routes using iBGP/eBGP as the client application. BFD Multihop provides continuity check (CC) on arbitrary paths spanning multiple network hops and provides failure notifications for Multihop protocols like BGP (iBGP: VRF and non-VRF and eBGP: VRF and non-VRF), MPLS Traffic Engineering, and LDP. The Cisco IOS XR Software BFD MHv6 implementation is in accordance with IETF RFC5883 for IPv6 networks.
BFD support for IPv6 Multihop is on a par with the BFD support for IPv4 Multihop (BFD MHv4). BFD MHv6 is supported on Cisco CRS-3 Modular Services line card and Cisco CRS Modular Services Card line card. The minimum interval for BFD Multihop is 50 milliseconds on Cisco CRS-3 Modular Services line card and 100 milliseconds on Cisco CRS Modular Services line card.
For more information on configuring BFD IPv6 Multihop, see the Implementing Bidirectional Forwarding Detection chapter in the Cisco IOS XR Routing Configuration Guide for the Cisco CRS Router. For complete command reference of the BFD IPv6 Multihop, see the Bidirectional Forwarding Detection Commands chapter in the Cisco IOS XR Routing Command Reference for the Cisco CRS Router.
BFD over MPLS Traffic Engineering LSPs
Bidirectional Forwarding Detection ( BFD) over MPLS Traffic Engineering Label Switched Paths (LSPs) feature in Cisco IOS XR Software detects MPLS Label Switched Path LSP data plane failures. Since the control plane processing required for BFD control packets is relatively smaller than the processing required for LSP Ping messages, BFD can be deployed for faster detection of data plane failure for a large number of LSPs.
The BFD over MPLS TE LSPs implementation in Cisco IOS XR Software is based on RFC 5884: Bidirectional Forwarding Detection (BFD) for MPLS Label Switched Paths (LSPs). LSP Ping is an existing mechanism for detecting MPLS data plane failures and for verifying the MPLS LSP data plane against the control plane. BFD can be used for for detecting MPLS data plane failures, but not for verifying the MPLS LSP data plane against the control plane. A combination of LSP Ping and BFD provides faster data plane failure detection on a large number of LSPs.
For more information on configuring BFD over MPLS Traffic Engineering LSPs, see the Implementing Bidirectional Forwarding Detection chapter in the Cisco IOS XR Routing Configuration Guide for the Cisco CRS Router. For complete command reference of the BFD over MPLS Traffic Engineering LSPs commands, see the Bidirectional Forwarding Detection Commands chapter in the Cisco IOS XR Routing Command Reference for the Cisco CRS Router.
BGP VRF Dynamic Route Leaking
The Border Gateway Protocol (BGP) dynamic route leaking feature provides the ability to import routes between the default-vrf (Global VRF) and any other non-default VRF, to provide connectivity between a global and a VPN host. The import process installs the Internet route in a VRF table or a VRF route in the Internet table, providing connectivity.
The dynamic route leaking is enabled by:
- Importing from default-VRF to non-default-VRF, using the import from default-vrf route-policy route-policy-name [advertise-as-vpn] command in VRF address-family configuration mode. If the advertise-as-vpn option is configured, the paths imported from the default-VRF to the non-default-VRF are advertised to the PEs as well as to the CEs. If the advertise-as-vpn option is not configured, the paths imported from the default-VRF to the non-default-VRF are not advertised to the PE. However, the paths are still advertised to the CEs.
- Importing from non-default-VRF to default VRF, using the export to default-vrf route-policy route-policy-name command in VRF address-family configuration mode.
For more information on configuring VRF Dynamic Route Leaking, see the Implementing BGP chapter in the Cisco IOS XR Routing Configuration Guide for the Cisco CRS Router. For complete command reference of the commands used for configuring and displaying Dynamic Route Leaking, see the BGP Commands chapter in the Cisco IOS XR Routing Command Reference for the Cisco CRS Router.
Flexible L3VPN Label Allocation Mode
The flexible L3VPN label allocation feature provides the ability to set label allocation mode using a route-policy, where different allocation modes can be used for different sets of prefixes. Thus, label mode can be chosen based on arbitrary match criteria such as prefix value and community.
Use the label mode command to set the MPLS/VPN label mode based on prefix value. The Label-Mode attach point enables you to choose label mode based on any arbitrary criteria.
For more information on Label-Mode attachpoint, see the Implementing Routing Policy chapter in the Cisco IOS XR Routing Configuration Guide for the Cisco CRS Router. For complete command reference of the set label-mode command, see the Routing Policy Language Commands chapter in the Cisco IOS XR Routing Command Reference for the Cisco CRS Router. For complete command reference of the label mode and label-allocation-mode commands, see the BGP Commands chapter in the Cisco IOS XR Routing Command Reference for the Cisco CRS Router.
IS-IS IPv6 Loop Free Alternate Fast Re-route
The IPv6 Loop Free Alternate fast Re-route (IPv6 LFA FRR) feature supports fast re-route (FRR) for IPv6 unicast in Cisco IOS XR Software. IPv6 FRR helps to minimize traffic loss during convergence for pure IPv6 unicast prefixes. The IPv6 LFA FRR supports both per-prefix LFA and per-link LFA modes. IPv6 LFA FRR for IS-IS is enabled by configuring the fast re-route commands under the IS-IS IPv6 address family configuration mode.
For more information on configuring IS-IS IPv6 Loop Free Alternate Fast Re-route, see the Implementing IS-IS chapter in the Cisco IOS XR Routing Configuration Guide for the Cisco CRS Router. For complete command reference of the IS-IS IPv6 Loop Free Alternate Fast Re-route commands, see the BGP Commands chapter in the Cisco IOS XR Routing Command Reference for the Cisco CRS Router.
IS-IS Link-group
The IS-IS link-group feature allows operators to define a set of links belonging to a group. The group is identified by a link-group profile. In that group, when the total number of ‘UP’ links falls below a certain value, the IS-IS will raise the link metric by a pre-defined ‘offset’ value for all the links in this group. Thus it discourages the traffic going over the set of links where the total physical bandwidth is reduced during the network operation. When the total number of ‘UP’ links is back to above certain number, the IS-IS will restore the link metric to corresponding configured value for all the links in this group.
For more information on configuring IS-IS link-group, see the Implementing IS-IS chapter in the Cisco IOS XR Routing Configuration Guide for the Cisco CRS Router. For complete command reference of IS-IS link-group commands, see the IS-IS Commands chapter in the Cisco IOS XR Routing Command Reference for the Cisco CRS Router.
IS-IS IP/LDP Remote Loop Free Alternate Fast Re-route
The IP/LDP remote loop free alternate fast re-route (rLFA FRR) feature enables computation of non-directly connected neighbor (more than one hop away) as LFA backup path to protect a given prefix’s primary path, and setting up of labeled [backup] LSP with the remote next-hop for the protected prefix. The rLFA FRR helps to minimize traffic loss in some topologies (example- ring topology) during convergence after a failure triggered topology change.
The use of a non-directly connected neighbor as LFA backup/next-hop is termed as Remote LFA or Extended LFA. For a given protected link, the IGP computes remote LFA backup by means of PQ algorithm. The IGP updates the routing information base (RIB) [ per-prefix ] with LFA protection information [per-path]. The LDP initiates/establishes a targeted session with the remote LFA [PQ] node to exchange labels for prefixes. The LDP also sets up MPLS forwarding for protected prefixes along with their remote LFA/PQ backup paths, if any. Upon FRR trigger, pre-programmed remote LFA backup path is activated to achieve convergence (within 50 milliseconds) and is used until the IGP converges to new primary path(s).
For more information on configuring IS-IS IP/LDP Remote Loop Free Alternate Fast Re-route, see the Implementing IS-IS chapter in the Cisco IOS XR Routing Configuration Guide for the Cisco CRS Router. For complete command reference of the IS-IS IP/LDP Remote Loop Free Alternate Fast Re-route commands, see the IS-IS Commands chapter in the Cisco IOS XR Routing Command Reference for the Cisco CRS Router.
LISP Common Control Plane
Locator/ID Separation Protocol (LISP) common control plane feature introduces a LISP control plane that is same as the IOS control plane. Cisco IOS XR Software and Cisco IOS XR and Cisco IOS platforms share a common LISP control plane.
OSPF IP/LDP Remote Loop Free Alternate Fast Re-route
The IP/LDP remote loop free alternate fast re-route (rLFA FRR) feature enables computation of non-directly connected neighbor (more than one hop away) as LFA backup path to protect a given prefix’s primary path, and setting up of labeled [backup] LSP with the remote next-hop for the protected prefix. The rLFA FRR helps to minimize traffic loss in some topologies (example- ring topology) during convergence after a failure triggered topology change.
The use of a non-directly connected neighbor as LFA backup/next-hop is termed as Remote LFA or Extended LFA. For a given protected link, the IGP computes remote LFA backup by means of PQ algorithm. The IGP updates the routing information base (RIB) [ per-prefix ] with LFA protection information [per-path]. The LDP initiates/establishes a targeted session with the remote LFA [PQ] node to exchange labels for prefixes. The LDP also sets up MPLS forwarding for protected prefixes along with their remote LFA/PQ backup paths, if any. Upon FRR trigger, pre-programmed remote LFA backup path is activated to achieve convergence (within 50 milliseconds) and is used until the IGP converges to new primary path(s).
For more information on configuring IS-IS IP/LDP Remote Loop Free Alternate Fast Re-route, see the Implementing OSPF chapter in the Cisco IOS XR Routing Configuration Guide for the Cisco CRS Router. For complete command reference of the IS-IS IP/LDP Remote Loop Free Alternate Fast Re-route commands, see the OSPF Commands chapter in the Cisco IOS XR Routing Command Reference for the Cisco CRS Router.
OSPF Local Uloop Avoidance
The OSPF local uloop avoidance feature helps to avoid local uloop that happens between the node where link UP/DOWN event happened and its neighbor. Configure the microloop avoidance {protected} and the microloop avoidance rib-update-delay delay in ms commands to configure local uloop avoidance mechanism.
If microloop avoidance is enabled, new primary paths are not added to the RIB during SPF, but the installation is delayed. This mechanism is activated only for a first adjacency DONW event following the stable condition. Specify the protected keyword uloop avoidance is only applied to prefixes which have a valid backup path for each primary path.
Configure microloop avoidance rib-update-delay to specify the interval after which the new primary paths will be installed in RIB.
For complete command reference of the OSPF uloop avoidance commands, see the OSPF Commands chapter in the Cisco IOS XR Routing Command Reference for the Cisco CRS Router.
OSPFv2 Autoroute Exclude
The OSPFv2 Autoroute Exclude feature allows specific destinations and prefixes to route off of TE tunnels, while other prefixes can still be forced to use TE tunnels. Prefixes that are excluded will never use a TE tunnel path. Only native, non-TE paths will be downloaded to RIB for such routes. Use the mpls traffic-eng autoroute-exclude command to enable autoroute exclude.
OSPFv2 Unequal Cost Load Balancing
Unequal Cost Load Balancing feature in Cisco IOS XR OSPFv2 feature enables Unequal Cost Multipath (UCMP) calculation based on configured prefix-list and based on variance factor. UCMP can be calculated for selected prefixes and the calculation can be excluded for paths if the outgoing interface of the UCMP paths is excluded from being used for UCMP. The calculated UCMP paths are then installed in the routing information base (RIB) subject to the max-path limit.
OSPFv3 Loop Free Alternate Fast Re-route
The OSPFv3 Loop Free Alternate fast Re-route (OSPFv3 LFA FRR) feature supports fast re-route (FRR) for OSPFv3 protocol Cisco IOS Software. OSPFv3 FRR helps to minimize traffic loss during convergence for pure IPv6 unicast prefixes. The OSPFv3 LFA FRR supports both per-prefix LFA and per-link LFA modes. OSPFv3 LFA FRR is enabled by configuring the fast re-route commands under the Router OSPFv3 configuration mode.
For more information on configuring OSPFv3 Loop Free Alternate Fast Re-route, see the Implementing OSPF chapter in the Cisco IOS XR Routing Configuration Guide for the Cisco CRS Router. For complete command reference of the OSPFv3 Loop Free Alternate Fast Re-route commands, see the OSPFv3 Commands chapter in the Cisco IOS XR Routing Command Reference for the Cisco CRS Router.
Match tag Support for OSPF distribute-list in
The Cisco IOS XR Software Route-policy extends match tag support of OSPF distribute-list in command. The "if tag..." statements can be used in distribute-list in route-policy. The matching on route tag supports operators "eq/ge/is/le". Operator "in" is not supported.
For more information on distribute-list in attachpoint, see the Implementing Routing Policy chapter in the Cisco IOS XR Routing Configuration Guide for the Cisco CRS Router. For complete command reference of the distribute-list in command, see the OSPF Commands chapter in the Cisco IOS XR Routing Command Reference for the Cisco CRS Router.
VPN Route Limit
The VPN route limit feature provides the ability to set a limit on the number of prefixes to be accepted from a BGP "customer" (a BGP neighbor) for VPNv4 or VPNv6 address families. Once the limit is reached, all subsequent routes received from the customer are dropped, no session-reset is established, and route refresh information are not sent. VPN route limit ensures that the route-reflector (RR) retains only a specified number of unique network entries for each VPN, where VPN is defined by a set of route-targets (RTs). BGP keeps a route count per unique set of RTs . The count indicates the number of prefixes (nets) that has one or more paths with the given RT-set. When a VPN exceeds the configured limit, all subsequent routes learned from that VPN are dropped. The drop action is restricted to the VPN that exceeds the limit.
Non-stop routing (NSR) is not supported with the VPN route limit feature. When VPN route limit is enabled, Active and Standby RPs will have different prefixes and paths because both the RPs receive the updates independently and do not guarantee the sequence of the prefixes. So, NSR is not supported as traffic is lost when RP fail over happens.
For more information on configuring VPN Route Limit, see the Implementing BGP chapter in the Cisco IOS XR Routing Configuration Guide for the Cisco CRS Router. For complete command reference of the VPN Route Limit commands, see the BGP Commands chapter in the Cisco IOS XR Routing Command Reference for the Cisco CRS Router.
VRF Import Policy Enhancement
The VRF RPL based import policy feature provides the ability to perform import operation based solely on import route-policy, by matching on route-targets (RTs) and other criteria specified within the policy. No need to explicitly configure import RTs under global VRF-address family configuration mode.
Use the source rt import-policy command under VPN address-family configuration mode to enable this feature.
For more information on configuring VRF Import Policy Enhancement, see the Implementing Routing Policy chapter in the Cisco IOS XR Routing Configuration Guide for the Cisco CRS Router. For complete command reference of the VRF RPL Based Import Policy, see the Routing Policy Language Commands chapter in the Cisco IOS XR Routing Command Reference for the Cisco CRS Router.
Virtual Connection Type 4 Support with BGP Auto-discovery
Support has been added for VC type 4 in VPLS with BGP Autodiscovery. A new command transport-mode vlan passthrough has been added to support this feature. This command is configured in the bridge domain configuration submode.
For more information on enabling VC type 4 for BGP autodiscovery, see the Implementing Multipoint Layer 2 Services module in the Cisco ASR 9000 Series Aggregation Services Router L2VPN and Ethernet Services Configuration Guide. For more information on commands to enable VC type 4, see the Cisco ASR 9000 Series Aggregation Services Router L2VPN and Ethernet Services Command Reference.
Auto-IP Configuration for nV Satellite System
The Auto IP feature improves the plug-and-play set up of an nV satellite system. With the Auto IP feature, IP connectivity to the satellite is automatically provisioned. As a result:
- The nV Satellite Loopback interface is created on the host
- Loopback interface is given an IP address from a private satellite VRF
- Satellite fabric links are unnumbered to the loopback interface
- The IP address assigned to satellite is auto-generated from the satellite VRF
Hence, in the case of Auto IP, you do not need to provide IP address on the nv satellite global configuration and on the ICL. But in the case of manual IP, you need to provide IP address on the nV satellite global configuration and on ICL.
NoteYou can also override the Auto IP feature by using the standard IP configuration.
CRS-3 Satellite System
The Cisco CRS-3 satellite system provides a solution in which one or more satellite switches complement a Cisco CRS-3 router to collectively realize a single virtual switching/routing system. In this system, the satellite switches act under the management control of the Cisco CRS-3 router. The complete configuration and management of the satellite chassis and features is performed through the control plane and management plane of the Cisco CRS-3 Router, which is referred to as the host. This satellite system provides:
- 44 Gigabit Ethernet ports that are used as satellite access ports
- 4 TenGigabit Ethernet ports that are used as ICL with the CRS
Only Cisco CRS-3 Modular Services Line Card with fixed PLIM (14x10GE and 20x10GE) can be used to interconnect with the Satellite boxes. For more information on the 10 Gigabit Ethernet line cards supported on the Cisco CRS Carrier Routing System 16-Slot Line Card Chassis and the Cisco CRS Carrier Routing System 8-Slot Line Card Chassis, refer to the Cisco CRS Carrier Routing System Ethernet Physical Layer Interface Module Installation Note.
Carrier Grade Services Engine-Plus PLIM
The Carrier Grade Services Engine-Plus (CGSE-Plus) is a new mutli-service PLIM that performs Layer 4 to Layer 7 services with a packet processing speed of 80 Gbps. CGSE-Plud PLIM is supported on CRS-MSC-140 and CRS-FP140 cards on CRS-3 single chassis. CGSE-Plus PLIM supports NAT44 and 6rd features.
For more information about the CGSE Plus PLIM, see the Implementing Carrier Grade IPv6 on Cisco IOS XR Software module in the Cisco IOS XR Carrier Grade NAT Configuration Guide for the Cisco CRS Router.
Multi-Chassis Carrier Grade Services Engine
The Carrier Grade Services Engine (CGSE) line card is supported in a multi-chassis configuration.
For more information about the CGSE Multi Chassis feature, see the Implementing Carrier Grade IPv6 on Cisco IOS XR Software module in the Cisco IOS XR Carrier Grade NAT Configuration Guide for the Cisco CRS Router.
MPLS OAM Support for BGP 3107
The MPLS OAM Support for BGP 3107 feature provides support for ping, traceroute and treetrace (traceroute multipath) operations for LSPs signaled via BGP for the IPv4 unicast prefix FECs in the default VRF, according to the RFC 3107 - Carrying Label Information in BGP-4. This feature adds support for MPLS OAM operations in the seamless MPLS architecture deployments, i.e., combinations of BGP and LDP signaled LSPs.
For more information about ping and traceroute, see Implementing MPLS OAM chapter in the Cisco IOS XR MPLS Configuration Guide for the Cisco CRS Router. For more information about ping and traceroute commands, see MPLS OAM Commands chapter in the Cisco IOS XR MPLS Command Reference for the Cisco CRS Router.
Policy-Based Tunnel Selection
Policy-Based Tunnel Selection (PBTS) provides a mechanism that lets you direct traffic into specific TE tunnels based on different criteria. PBTS will benefit Internet service providers (ISPs) who carry voice and data traffic through their MPLS and MPLS/VPN networks, who want to route this traffic to provide optimized voice service.
PBTS works by selecting tunnels based on the classification criteria of the incoming packets, which are based on the IP precedence, experimental (EXP), or type of service (ToS) field in the packet. When there are no paths with a default class configured, this traffic is forwarded using the paths with the lowest class value. PBTS supports up to seven (exp 1 - 7) EXP values associated with a single TE tunnel.
For more information on configuring PBTS, refer to the Implementing MPLS Traffic Engineering chapter in the Cisco IOS XR MPLS Configuration Guide for the Cisco CRS Router. For more information on commands for configuring PBTS, refer to the MPLS Traffic Engineering Commands chapter in the Cisco IOS XR MPLS Command Reference for the Cisco CRS Router.
Bundle QoS Granularity
The Bundle QoS Granularity feature supports shaper and policer rate configuration in units of per-thousand/per-million which provides the ability to provision shape/police rates down to 1 Mbps on link aggregation (LAG) interfaces even with 100 GE bundle members.
Bundle QoS granularity supports both, ingress and egress policy-maps. The supported bundle-member types are, 100GE, 10GE, 40GE, OC768, OC192.
Automatic Multicast Tunneling
Automatic Multicast Tunneling (AMT) provides a method to tunnel multicast data over a unicast network . The tunneling is performed between AMT Relays and AMT Gateways, using UDP (User Datagram Protocol) encapsulation. This enables service providers and their customers to participate in delivering multicast traffic even in the absence of end-to-end multicast connectivity.
Netflow over BVI
NetFlow monitoring on Bridge-Group Virtual Interface (BVI) enables traffic monitoring, capacity planning, accounting, security threat detection and billing.
For more information about the NetFlow over BVI feature, see the Configuring NetFlow module in the Cisco IOS XR Netflow Configuration Guide for the Cisco CRS Router.For complete command reference of NetFlow, see the NetFlow Commands chapter in the Cisco IOS XR Netflow Command Reference for the Cisco CRS Router.
Destination-based NetFlow Accounting
Destination-based NetFlow accounting (DBA) is a usage-based billing application that tracks and records traffic according to its destination and enables service providers to do destination-specific accounting and billing. The destination-based NetFlow accounting record includes the destination peer autonomous system (AS) number and the BGP next-hop IP address.
IPv4 DBA is already supported in CRS. In Release 4.3.1, the support for IPv6 DBA support is added.
For more information about the IPv6 Destination-based NetFlow Accounting feature, see the Configuring NetFlow module in the Cisco IOS XR Netflow Configuration Guide for the Cisco CRS Router.For complete command reference of IPv6 Destination-based NetFlow Accounting commands, see the NetFlow Commandschapter in the Cisco IOS XR Netflow Command Reference for the Cisco CRS Router.
ISSU Support
For more information regarding ISSU, refer to the Upgrading and Managing Software module in the Cisco IOS XR System Management Configuration Guide for the Cisco CRS Router.
Flexible CLI Configuration Groups
Flexible command line interface (CLI) configuration groups provide the ability to minimize repetitive configurations by defining a series of configuration statements in a configuration group, and then applying this group to multiple hierarchical levels in the router configuration tree.
Flexible CLI configuration groups utilize regular expressions that are checked for a match at multiple submodes of the configuration tree based on where the group is applied within the hierarchy. If a match is found at a configuration submode, the corresponding configuration defined in the group is inherited within the matched submode.
Flexible CLI configuration groups also provide an auto-inheritance feature. Auto-inheritance means that any change done to a CLI configuration group is automatically applied to the configuration in any matched submodes that have an apply-group at that hierarchical level. This allows you to make a configuration change or addition once, and have it applied automatically in multiple locations, depending on where you have applied the flexible CLI configuration group.
For more information on flexible CLI configurations, see the Configuring Flexible Command Line Interface Configuration Groups module in the Cisco IOS XR System Management Configuration Guide for the Cisco CRS Router. For command information, refer to the Configuration Management Commands module in the Cisco IOS XR System Management Command Reference for the Cisco CRS Router.
SSHv2 Client Keyboard-Interactive Authentication
An authentication method in which the authentication information is entered using a keyboard is known as keyboard-interactive authentication. This method is an interactive authentication method in the SSH protocol. This type of authentication allows the SSH client to support different methods of authentication without having to be aware of their underlying mechanisms.
Currently, the SSHv2 client supports the keyboard-interactive authentication. This type of authentication works only for interactive applications.
For more information about the SSHv2 Client Keyboard-Interactive Authentication feature, see the Implementing Secure Shell module in the Cisco IOS XR System Security Configuration Guide for the Cisco CRS Router.For complete command reference of SSHv2 Client Keyboard-Interactive Authentication commands, see the Secure Shell Commandschapter in the Cisco IOS XR System Security Command Reference for the Cisco CRS Router
Hardware Features Introduced in Cisco IOS XR Software Release 4.3.1 for Cisco CRS Router
The following hardware features were introduced in Cisco IOS XR Software Release 4.3.1 on the Cisco CRS Router:
- CRS Back-to-Back System on 8-Slot CRS-3 You can connect two 8-slot chassis together using fabric cards and cables. The two chassis then act as a single routing entity, expanding the system from 8 to 16 slots. Cisco IOS XR Software Release 4.3.1 introduces a new fabric card, Cisco CRS Series 8-Slot Back-to-Back Fabric Card (CRS-8-FC140/M), to support the CRS Back-to-Back System. Compared to a 2+1 multichassis system, the CRS Back-to-Back System connects two LCCs without the fabric card chassis (FCC) or S2 cards. Instead, two LCCs are connected using a set of back-to-back cables. This system has all of the benefits of a 2+1 multichassis system without an FCC. It provides the same functionality and scale of a 2+1 multichassis system. The CRS Back-to-Back System is only supported on CRS-3 with Performance Router Processors or PRPs. For more general CRS Back-to-Back System hardware information, refer to the Cisco CRS-3 Carrier Routing System 8-Slot Back-to-Back Cabling and Upgrade Guide.
- ASR 9000v Satellite System support on the Cisco CRS-3 Router Cisco IOS XR Software Release 4.3.1 introduces support for the Cisco ASR 9000v (a satellite shelf system) on the Cisco CRS-3 Router.

Important Notes on Cisco IOS XR Software and Cisco CRS Router
- Default timestamp setting—The timestamp prompt that precedes console output is enabled by default. To disable the timestamp prompt, use the no service timestamp command. For more information, refer to the Cisco IOS XR System Management Command Reference for the Cisco CRS Router .
- Country-specific laws, regulations, and licenses—In certain countries, use of these products may be prohibited and subject to laws, regulations, or licenses, including requirements applicable to the use of the products under telecommunications and other laws and regulations; customers must comply with all such applicable laws in the countries in which they intend to use the products.
- Field replacable unit (FRU) removal—For all card removal and replacement (including fabric cards, line cards, fan controller, and RP) follow the instructions provided by Cisco to avoid impact to traffic. See the Cisco IOS XR Getting Started Guide for the Cisco CRS Router for procedures.
- Exceeding Cisco testing—If you intend to test beyond the combined maximum configuration tested and published by Cisco, contact your Cisco Technical Support representative to discuss how to engineer a large-scale configuration maximum for your purpose.
- mpls traffic engineering igp-intact command—This command must be used only when policy based tunnel selection is configured for all tunnels originating on the device. This CLI needs to be turned on under IGP (OSPF/ISIS) under the respective AFI.
- The following TE Path option attribute commands are not supported on the Cisco CRS-1 Series Router:
- BFD IPv6 UDP Checksum Calculation—In Cisco IOS XR Software Release 3.9, you turn the BFD IPv6 UDP checksum calculation on and off:
- To disable the BFD IPv6 UDP checksum calculation:
RP/0/RP0/CPU0:router(config)#bfd RP/0/RP0/CPU0:router(config-bfd)#ipv6 checksum disable RP/0/RP0/CPU0:router(config-bfd)#end- To enable BFD IPv6 UDP checksum calculation:
RP/0/RP0/CPU0:router(config)#bfd RP/0/RP0/CPU0:router(config-bfd)#no ipv6 checksum disable RP/0/RP0/CPU0:router(config-bfd)#end- On upgrading Cisco IOS XR Software from 3.6.2 to 4.0.0 the MAC address assigned to physical interfaces changes. This is required because prior to Cisco IOS XR Software Release 3.8.4 the MAC address assigned to the bundle interface was taken from the first member's MAC address. If this bundle member is removed from the bundle, the bundle gets a new MAC address, which results in traffic loss due to ARP resolution. Beginning in Cisco IOS XR Software Release 3.8.4, a pool of MAC addresses are assigned to the bundle interfaces by the bundlemgr process during bundle interface creation.
- Deactivation of os-mbi dependent (Nonreload) SMU fails—Backing out the non reload os-mbi SMU fails because deactivation runs out of memory (activation did not release some memory, which stayed at 38 MB). This failure to activate or deactivate the SMU due to insufficient SP resources impacts SP cards on CRS.
- When configuring the Label Distribution Protocol (LDP) graceful restart (GR) process in a network with multiple [link and/or targeted] LDP hello adjacencies with the same neighbor, make sure that GR is activated on the session before any hello adjacency times out due to neighbor control plane failures. One way of achieving this is by configuring a lower session hold time between neighbors such that session time out always occurs before hello adjacency can time out. Cisco recommends setting LDP session hold time using the following formula: LDP session hold time <= (Hello hold time - Hello interval) * 3 This means that for default values of 15/5 seconds respectively for the link Hello hold time and the Hello interval, the LDP session hold time should be set to 30 seconds or less. For more information, refer to the Implementing MPLS Label Distribution Protocol on Cisco IOS XR Software section of the Cisco IOS XR MPLS Configuration Guide for the Cisco CRS Router.

DWDM Configuration Management
NoteThis section describes the new DWDM configuration requirements in Cisco IOS XR 3.9.0 and later releases. It does not describe all updates to the DWDM feature. For more information about DWDM configuration, refer to the Configuring Dense Wavelength Division Multiplexing Controllers on Cisco IOS XR Software module in the Cisco IOS XR Interface and Hardware Component Configuration Guide for the Cisco CRS Router.
Cisco IOS XR Software Release 3.9.0 introduced new commands in addition to an important change to the default laser state for all of the DWDM physical layer interface modules (PLIMs) supported on the Cisco CRS-1 and CRS-3 routers, which impacts the required configuration to support those cards.
This change affects all models of the following hardware on the Cisco CRS-1 router:
This change affects all models of the following hardware on the Cisco CRS-3 router:
- Cisco 1-Port 100GE OTU4 IPoDWDM PLIM
- Cisco 4-Port 40-GE OTU3 OTN/LAN PLIM
- Cisco 2-Port 40-GE OTU3 OTN/LAN PLIM
The g709 fec high-gain and g709 fec long-haul commands are added under DWDM configuration to configure the new high-gain FEC mode and long-haul FEC mode for Cisco 1-Port 100GE OTU4 IPoDWDM PLIM.
The following is an example of configuring the g709 fec high-gain command under DWDM configuration to configure the new high-gain FEC mode:
RP/0/RP0/CPU0:router# configure RP/0/RP0/CPU0:router(config)# controller dwdm <> RP/0/RP0/CPU0:router(config)# g709 fec high-gain RP/0/RP0/CPU0:router(config)# commitThe following is an example of configuring the g709 fec long-haul command under DWDM configuration to configure the new long-haul FEC mode:
RP/0/RP0/CPU0:router# configure RP/0/RP0/CPU0:router(config)# g709 fec long-haul RP/0/RP0/CPU0:router(config)# commit

- Configuration Examples in Cisco IOS XR Software Release 3.9.0 and Later Releases
Important DWDM Changes in Cisco IOS XR Software Release 3.9.0 and Later Releases
- The laser off and shutdown (DWDM) commands are replaced by the admin-state-out-of-service command.
- The default state of the laser has changed from "On" to "Off" for all PLIMs. Therefore, the laser for all DWDM controllers must explicitly be turned on using the admin-state in-service command in DWDM configuration mode
Configuration Examples in Cisco IOS XR Software Release 3.9.0 and Later Releases
This section provides configuration examples for turning on and off the laser on a DWDM PLIM.
Turning On the Laser: Example
NoteThis is a required configuration beginning in Cisco IOS XR Software Release 3.9.0. The DWDM PLIMs will not operate without this configuration.
The following example shows how to turn on the laser and place a DWDM port in In Service (IS) state:
RP/0/RP0/CPU0:router# configure RP/0/RP0/CPU0:router(config)# controller dwdm 0/1/0/1 RP/0/RP0/CPU0:router(config-dwdm)# admin-state in-service RP/0/RP0/CPU0:router(config-dwdm)# commitTurning Off the Laser: Example
NoteThis configuration replaces the laser off and shutdown (DWDM) configuration commands.
The following example shows how to turn off the laser, stop all traffic and place a DWDM port in Out of Service (OOS) state:
RP/0/RP0/CPU0:router# configure RP/0/RP0/CPU0:router(config)# controller dwdm 0/1/0/1 RP/0/RP0/CPU0:router(config-dwdm)# admin-state out-of-service RP/0/RP0/CPU0:router(config-dwdm)# commitMinimum Flash Disk Requirements When Upgrading to Release 4.3.1
Cisco IOS XR Software Release 4.3.1 requires a minimum of 4-GB Flash Disk. This release also provides an upgrade option to 16-GB Flash Disk. 1-GB and 2-GB Flash Disks are no longer supported with this release. For information on End-of-Sale and End-of-Life Announcement for the Cisco CRS-1 PCMCIA Flash Disk 2 GB, refer to: http://www.cisco.com/en/US/prod/collateral/routers/ps5763/end_of_life_notice_c51-681333.html
To upgrade from a 1-GB or 2-GB to a greater Flash Disk, refer to the Flash Disk Upgrade Tasks link on the following Cisco CRS router Installation and Upgrade URL: http://www.cisco.com/en/US/products/ps5763/prod_installation_guides_list.html
For Cisco CRS routers, change to FAT32 in order to partition a 4 GB Flash Disk as a 3.5 GB and 0.5 GB partition. This type of partition is recommended in order to create a partition with more than 2 GB of flash space. Disk partitioning has been supported from Cisco IOS XR Software Release 3.6 onwards. For more information, refer to the Turbo Boot Appendix of the Cisco CRS-1 Carrier Routing System to Cisco CRS-3 Carrier Routing System Migration Guide .
Additional upgrade instructions for the Cisco CRS router are available from http://www.cisco.com/web/Cisco_IOS_XR_Software/pdf/ReplacingPCMCIACardOnCRS-1.pdf.
Caveats
Caveats describe unexpected behavior in Cisco IOS XR Software releases. Severity-1 caveats are the most serious caveats; severity-2 caveats are less serious.
This section contains caveats that are generic to the Cisco IOS XR Software Release 4.3.1 and those specific to the Cisco CRS-1 router and the Cisco CRS-3 router.
- Cisco IOS XR Caveats
- Caveats Specific to the Cisco CRS Router
- Caveats Specific to the Cisco CRS-3 Router
Cisco IOS XR Caveats
The following open caveats apply to Cisco IOS XR Software Release and are not platform specific:
- CSCud77196 Basic Description: BFD Bundle interface goes down after performing shut/noshut operation. Symptom The status of the Bidirectional Forwarding Detection (BFD) sessions on the bundle is up and immediately goes down on all member links. It happens, when the bundle interface shuts BFD sessions or continues to operate on it without shutting it down. Conditions: The issue exists due to BFD timeout, only for few scenarios. The BFD packets drop occurs due to delays in Forwarding Information Base (FIB) route install. Workaround: The status of the bundle is up again when the bundle interface repeatedly shuts down the BFD sessions or continues to operate on it.
- CSCue78677 Basic Description: Memory leak seen on XML dedicated agent. Symptom System fails to properly free the memory allocated while processing the "get XML query" query, provided with large number of Broader Gateway Protocol (BGP) configurations. It happens even after the XML session is terminated. Note: The xml_tty_agent process leaks some chunk of memory, for each iteration, for example 328 bytes of memory. Conditions: Execute the "get XML query" for BGP with large number of BGP configurations. Workaround: None.
- CSCuf83074 Basic Description: sysmgr reports multiple process restarts post RPFO. Symptom Multiple processes restart. Conditions: The issue persists during Route Processing (RP) fail over. Workaround: None.
- CSCug47099 Basic Description: install add operation fails, node fails to respond when completing disk checks. Symptom
Install add operation fails and displays the following messages:Conditions: The procedure is not available to reproduce the scenario. Workaround: Restart insthelper process by using the command process restart JID.
- Error: ERROR: Process insthelper has been performing an operation for a period of time so that the node failed to respond when completing the installation of packages within the system. Error: AFFECTED NODE(S): 0/RP1/CPU0 1/RP0/CPU0 1/RP1/CPU0.
- Node failed to respond when completing the disk checks. AFFECTED NODE(S): 0/RP0/CPU0 0/RP1/CPU0.
- CSCug72731 Basic Description: TI-MoFRR do not switch to Active after shutting (S1,G) RPF interface. Symptom
Reverse Path Forwarding (RPF) interface does not cause switch overs in the following two conditions:Conditions: Workaround: Install Software Maintenance Upgrades (SMU).- CSCug78374 Basic Description: mpls_lsd process memory leak on standby RP. Symptom mpls_lsd process memory leak on standby RP. Conditions: The memory leak issue on mpls_lsd process would be observed on scaled environments. Workaround: None.
Caveats Specific to the Cisco CRS Router
The following open caveats are specific to the Cisco CRS platform:
- CSCuf56390 Basic Description: BFD sessions flap upon DSC RPFO of MC8+1. Symptom During Route Processor Fail Over (RPFO) in a CRS multi-chassis system with scaled configuration, the IPv4 static, IPV6 static, BFD over bundle, and BFD over TE sessions flap: Conditions: The issue persists only during RPFO and on a multi-chassis scaled environment. Workaround: None. Recovery: The issue automatically recovers once the BFD sessions go down and come up.
- CSCug57035 Basic Description: The show mfib vrf default ipv6 hardware route olist detail ff18:23::1:14 location 0/1/CPU0 command loops infinitely. Symptom The show mfib vrf default ipv6 hardware route olist detail ff18:23::1:14 location 0/1/CPU0 command on the router leads to infinite loop. Conditions: The issue persists for all IPv6 routes. Workaround: None. Also, there is no operational or functional impact on the router.
- CSCug70476 Basic Description: Satellite interface configuration is lost after router reload. Symptom Satellite interface configurations are not available after router reload. Conditions: Ensure router reload is present with satellite configuration. Workaround: Restore the satellite interface configuration.
