Cisco IOS XR Software running on the Cisco ASR 9000 Series 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.
- Ethernet Services—The following Ethernet features are supported:
- Ethernet Virtual Connections (EVCs)
- Flexible VLAN classification
- Flexible VLAN translation
- IEEE bridging
- IEEE 802.1s Multiple Spanning Tree (MST)
- MST Access Gateway
- L2VPN
- Virtual Private LAN Services (VPLS), Hierarchical VPLS (H-VPLS), Virtual Private Wire Service (VPWS), Ethernet over MPLS (EoMPLS), pseudo wire redundancy, and multi segment pseudo wire stitching.
- 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) [including TE-FRR and TW Preferred Path], Resource Reservation Protocol (RSVP), Label Distribution Protocol (LDP), Targeted LDP (T-LDP), Differentiated Services (DiffServ)-aware traffic engineering, 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. The Cisco ASR 9000 Series Aggregation Services Router also supports Auto-Rendezvous Point (AutoRP), Multiprotocol BGP (MBGP), Multicast Source Discovery Protocol (MSDP), Internet Group Management Protocol Versions 2 and 3 (IGMPv2 and v3), and IGMPv2 and v3 snooping.
- Quality of Service (QOS)—This supports QoS mechanisms including policing, marking, queuing, random and hard traffic dropping, and shaping. Additionally, Cisco IOS XR supports modular QoS command-line interface (MQC). MQC is used to configure various QoS features on various Cisco platforms, including the Cisco ASR 9000 Series Aggregation Services Router. Supports the following:
- 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 Layer 2 and Layer 3 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 and OSPF, and nonstop forwarding (NSF).

Table 4 Cisco ASR 9000 Series Aggregation Services Router Supported Software Licenses Software License
Part Number
Cisco ASR 9000 Series Aggregation Services Router iVRF License
A9K-IVRF-LIC
Cisco ASR 9000 Series Aggregation Services Router Per Chassis Advanced Video License
A9K-ADV-VIDEO-LIC
Cisco ASR 9000 Series Aggregation Services Router Per Line Card Advanced Optical License
A9K-ADV-OPTIC-LIC
Cisco ASR 9000 Series Aggregation Services Router L3VPN License, Medium Queue and Low Queue Line Cards
A9K-AIP-LIC-B
Cisco ASR 9000 Series Aggregation Services Router L3VPN License, High Queue Line Cards

Note that error messages may display if features run without the appropriate licenses installed. For example, when creating or configuring VRF, if the A9K-IVRF-LIC license is not installed before creating a VRF, the following message displays:
RP/0/RSP0/CPU0:router#LC/0/0/CPU0:Dec 15 17:57:53.653 : rsi_agent[247]: %LICENSE-ASR9K_LICENSE-2-INFRA_VRF_NEEDED : 5 VRF(s) are configured without license A9K-iVRF-LIC in violation of the Software Right To Use Agreement. This feature may be disabled by the system without the appropriate license. Contact Cisco to purchase the license immediately to avoid potential service interruption.For Cisco license support, please contact your Cisco Sales Representative or Customer Service at 800- 553-NETS (6387) or 408-526-4000. For questions on the program other than ordering, please send e-mail to: cwm-license@cisco.com.
Cisco ASR 9000 Series Aggregration Services Router Right-To-Use (RTU) Licensing
Here are on-line locations of the Cisco ASR 9000 Series Aggregation Services Router Right-To-Use (RTU) licensing docs:http://www.cisco.com/en/US/docs/routers/asr9000/hardware/Prodlicense/A9k-AIP-LIC-B.html
http://www.cisco.com/en/US/docs/routers/asr9000/hardware/Prodlicense/A9k-AIP-LIC-E.html
NoteLayer 3 VPNs are only to be used after you have purchased a license. Cisco will enforce the RTU of L3VPNs in follow on releases. You should contact Cisco, or check the release notes for the follow on release before upgrading for directions on how to install the license as part of the upgrade - otherwise the L3VPN feature may be affected.
The activation of VRF capability still requires the use of the appropriate per line card license (A9K-IVRF-LIC / A9K-AIP-LIC-B / A9K-AIP-LIC-E). Please contact your sales representative for more details.
Firmware Support
To check the firmware code running on the Cisco ASR 9000 Series Router, run the show fpd package command in admin mode.
If upgrading from Release 3.7.3 or earlier releases, you may be expected to do a one-time FPD upgrade for any firmware images that may have changed since the last release. Refer to the documents at http://www.cisco.com/web/Cisco_IOS_XR_Software/index.html for upgrade instructions.

Software Features Introduced in Cisco IOS XR Software Release 5.1.0 for Cisco ASR 9000 Series Aggregation Service Router
BFD Dampening
Bidirectional Forwarding Detection (BFD) is a mechanism used by routing protocols to quickly realize and communicate the reachability failures to their neighbors. When BFD detects a reachability status change of a client, its neighbors are notified immediately. Sometimes it might be critical to minimize changes in routing tables so as not to impact convergence, in case of a micro failure. An unstable link that flaps excessively can cause other devices in the network to consume substantial processing resources, and that can cause routing protocols to lose synchronization with the state of the flapping link.
The BFD Dampening feature introduces a configurable exponential delay mechanism. This mechanism is designed to suppress the excessive effect of remote node reachability events flapping with BFD. The BFD Dampening feature allows the network operator to automatically dampen a given BFD session to prevent excessive notification to BFD clients, thus preventing unnecessary instability in the network. Dampening the notification to a BFD client suppresses BFD notification until the time the session under monitoring stops flapping and becomes stable.
Configuring the BFD Dampening feature, especially on a high-speed interface with routing clients, improves convergence time and stability throughout the network. BFD dampening can be applied to all types of BFD sessions, including IPv4/single-hop/multihop, Multiprotocol Label Switching-Transport Profile (MPLS-TP), and Pseudo Wire (PW) Virtual Circuit Connection Verification (VCCV).
BFD Session Dampening
You can configure the BFD Dampening feature at the BFD template level (both single-hop and multihop templates). Dampening is applied to all the sessions that use the BFD template. If you choose not to have a session to be dampened, you should use a new BFD template without dampening for a new session. By default, the dampening functionality is not enabled on a template.
BFD over IRB
In order for a VLAN to span a router, the router must be capable of forwarding frames from one interface to another, while maintaining the VLAN header. If the router is configured for routing a Layer 3 (network layer) protocol, it will terminate the VLAN and MAC layers at the interface on which a frame arrives. The MAC layer header can be maintained if the router bridges the network layer protocol. However, even regular bridging terminates the VLAN header.
Using the Integrated Routing Bridging (IRB) feature in Cisco IOS XR Software Release 5.1.0 or greater, a router can be configured for routing and bridging the same network layer protocol, on the same interface. This allows the VLAN header to be maintained on a frame while it transits a router from one interface to another. IRB provides the ability to route between a bridged domain and a routed domain with the Bridge Group Virtual Interface (BVI). The BVI is a virtual interface within the router that acts like a normal routed interface that does not support bridging, but represents the comparable bridge group to routed interfaces within the router. The interface number of the BVI is the number of the bridge group that the virtual interface represents. This number is the link between the BVI and the bridge group.
Because the BVI represents a bridge group as a routed interface, it must be configured only with Layer 3 (L3) characteristics, such as network layer addresses. Similarly, the interfaces configured for bridging a protocol must not be configured with any L3 characteristics.
BFD over IRB is a multipath single-hop session. In a BFD multipath session, BFD can be applied over virtual interfaces or between interfaces that are multihops away. The Cisco IOS XR Software BFD multihop is based on the RFC 5883—Bidirectional Forwarding Detection (BFD) for Multihop Paths. BFD over IRB is supported on IPv4 address, IPv6 global address, and IPv6 link-local address. The BFD over IRB is supported only in asynchronous mode and does not support echo mode. The BFD over IRB feature is supported only on the ASR 9000 enhanced Ethernet line cards.
EIGRP Multi-Instance
The Enhanced Interior Gateway Routing Protocol (EIGRP) Multi-Instance feature allows multiple process instances to handle different routing instances and service the same VRF. Each process instance handles the routing instances configured under it. The multiple EIGRP process instance implementation allows to configure the EIGRP using a virtual-name in addition to an autonomous-system number.
Graceful Restart for OSPFv3
The OSPFv3 Graceful Restart feature preserves the data plane capability in these circumstances:
- RP failure resulting in a switch-over to the backup processor
- Planned OSPFv3 process restart, such as a restart resulting from a software upgrade or downgrade
- Unplanned OSPFv3 process restart, such as a restart resulting from a process crash
This feature supports nonstop data forwarding on established routes while the OSPFv3 routing protocol restarts. Therefore, this feature enhances high availability of IPv6 forwarding.
Protocol Shutdown Mode
In this mode the OSPFv3 operation is completely disabled. This is accomplished by flushing self-originated link state advertisements (LSAs), immediately bringing down local OSPFv3-supported interfaces, and clearing the Link State Database (LSDB). The non-local LSDB entries are removed by OSPFv3, These are not flooded (MaxAged).
The protocol shutdown mode can be invoked either manually through the protocol shutdown command that disables the protocol instance or when the OSPFv3 process runs out of memory. These events occur when protocol shut down is performed:
- The local Router LSA and all local Link LSAs are flushed. All other LSAs are eventually aged out by other OSPFv3 routers in the domain.
- OSPFv3 neighbors that are currently exchanging their database with the local router are brought down with the Kill_Nbr event.
- Empty Hello packets are immediately sent to each neighbor that has an active adjacency.
- The LSA database from that OSPFv3 instance is cleared.
- All routes from RIB that were installed by OSPFv3 are purged.
- The router will not respond to any OSPF control packets it receives from neighbors while in protocol shutdown state.
Protocol Restoration
The method of restoring the protocol is dependent on the trigger that originally invoked the shut down. If the OSPFv3 was shut down using the protocol shutdown command, then use the no protocol shutdown command to restore OSPFv3 back to normal operation. If the OSPFv3 was shutdown due to a Critical Memory message from the sysmon, then a Normal Memory message from sysmon, which indicates that sufficient memory has been restored to the processor, restores the OSPFv3 protocol to resume normal operation.
These events occur when the OSPFv3 is restored:
OSPFv3 Sham Link Support for MPLS VPN
OSPFv3 sham link represents the VPN backbone as a single point-to-point connection between the two PEs. OSPFv3 treats the sham link as a point-to-point unnumbered interface, similar to virtual-link. When OSPFv3 sham link is configured, ensure that the route to the remote endpoint of the sham-link exists in the VRF RIB.
If the route to the remote endpoint exists, sham link interface is brought up. If the route to the remote endpoint of the sham-link is removed from the VRF RIB, OSPFv3 receives redistribution callback and brings the sham link down.
Graceful Restart Procedure over the Sham-link
OSPFv3 treats the sham link as any other interface during the switch-over or process restart. OSPFv3 assumes that all the configured sham links are UP and tries to form an adjacency over them.
If the sham link is down prior to the switch-over, OSPFv3 sends the Hello packets to the remote endpoint. Once the final convergence signal is received from the RIB, OSPFv3 keeps the sham link either up or down based on the BGP route for each configured sham link in the RIB.
OSPFv3 installs the high AD routes over the sham link only after the BGP convergence is complete.
Ethernet Data Plane Loopback
The Ethernet Data Plane Loopback feature allows you to test the services and throughput of an Ethernet port or a device using a test generator. You can verify the maximum rate of frame transmission with no frame loss. This feature allows bidirectional throughput measurement, and on-demand or out-of-service (intrusive) operation during service turn-up. This feature can be used for testing during service turn-up and troubleshooting of services after the turn-up.
For information on Ethernet Data Plane Loopback configuration, see the Cisco ASR 9000 Series Aggregation Services Router Interface and Hardware Component Configuration Guide.
Sampled Traffic Mirroring
Sampled Traffic Mirroring or Sampled SPAN is an extension of the SPAN feature which allows you to sample the packets based on a configured interval. Sampled SPAN can be applied on a physical port in order to include all the forwarding interfaces on that port. You can also configure the sampling rate of monitoring that is configured for each source port.
For more information on Sampled Traffic Mirroring, see the Cisco ASR 9000 Series Aggregation Services Router Interface and Hardware Component Configuration Guide.
Idle Timeout for IPoE and PPPoE Sessions
The Idle Timeout feature for IPoE and PPPoE sessions allows users to configure a maximum period of time that the subscriber sessions may remain idle. The subscriber sessions are terminated when this timeout period expires. The BNG monitors both the ingress and egress traffic for the determination of the idle time for the subscriber sessions. Control packets are not considered while determining session inactivity.
For more information about the Idle Timeout for IPoE and PPPoE Sessions feature, see the Configuring Subscriber Features chapter in the Cisco ASR 9000 Series Aggregation Services Router Broadband Network Gateway Configuration Guide. For complete command reference for this feature, see the Control Policy Commands chapter and Dynamic Template Commands chapter in the Cisco ASR 9000 Series Aggregation Services Router Broadband Network Gateway Command Reference.
Routing Support on Subscriber Sessions
Routing support on subscriber sessions allows dynamic routes to be added on an individual subscriber basis for IPoE sessions. This allows to forward traffic from the default Virtual Routing and Forwarding (VRF) towards the subscriber, or to access the routes behind the subscriber. As opposed to static routes, dynamic routes must be added and removed when subscribers are created and deleted. Dynamic routes can belong to a VRF other than that of the subscriber and they are supported for IPv4 subscribers only.
For more information about routing support on subscriber session, see the Configuring Subscriber Features chapter in the Cisco ASR 9000 Series Aggregation Services Router Broadband Network Gateway Configuration Guide.
Traffic Mirroring on Subscriber Session
BNG supports the Traffic Mirroring feature on subscriber session. Traffic mirroring, also known as Switched Port Analyzer (SPAN), enables a user to monitor Layer 2 network traffic passing in or out of a set of Ethernet interfaces. This allows the mirroring of packets that pass through a source interface to a specified destination interface. The destination interface may then be attached to a network analyzer for debugging.
For more information about the Traffic Mirroring on Subscriber Session feature, see the Configuring Subscriber Features chapter in the Cisco ASR 9000 Series Aggregation Services Router Broadband Network Gateway Configuration Guide. For complete command reference for this feature, see the Dynamic Template Commands chapter in the Cisco ASR 9000 Series Aggregation Services Router Broadband Network Gateway Command Reference.
Per-VLAN Rapid Spanning Tree
This feature is the IEEE 802.1w (RSTP) standard implemented per VLAN, and is also known as Rapid PVST or PVST+. A single instance of STP runs on each configured VLAN (if you do not manually disable STP). Each Rapid PVST+ instance on a VLAN has a single root switch. You can enable and disable STP on a per-VLAN basis when you are running Rapid PVST+.
PVRST uses point-to-point wiring to provide rapid convergence of the spanning tree. The spanning tree reconfiguration can occur in less than one second with PVRST (in contrast to 50 seconds with the default settings in the 802.1D STP).
For more information on configuring PVRST, see the Implementing Multiple Spanning Tree Protocol module in the Cisco ASR 9000 Series Aggregation Services Router L2VPN and Ethernet Services Configuration Guide. For more information on PVRST commands, see the Cisco ASR 9000 Series Aggregation Services Router L2VPN and Ethernet Services Command Reference.
Virtual Private LAN Services Label Switched Multicast
Virtual Private LAN Services (VPLS) is a Layer 2 based solution that efficiently sends multicast traffic over a multiprotocol label switching (MPLS) network. Point-to-point (P2P) pseudowires (PWs) are setup at PE routers participating in a VPLS domain to provide VPLS emulation. VPLS Label Switched Multicast (LSM) is an effective multicast solution for overcoming the limitations of ingress replication. This solution employs point-to-multipoint (P2MP) label switched path (LSP) in the MPLS network to transport multicast traffic over a VPLS domain. P2MP LSP minimizes the replication of packets and allows any replication in the network at the most optimal node.
For more information on configuring VPLS LSM, 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 configure VPLS LSM, see the Cisco ASR 9000 Series Aggregation Services Router L2VPN and Ethernet Services Command Reference.
DHCPv4 Server
The DHCPv4 server allocates network addresses and passes IP configuration parameters to dynamically-configured hosts.
When a client initiates a DHCP Discover request on its local Ethernet segment, the DHCP Server sends a notification to a Distributed Address Pool (DAPS) component requesting that it allocate addresses to clients from a specified pool. The DAPS selects a client address from the specified pool and returns it to the DHCP Server. The DHCP Server sends the allocated address through a DHCP OFFER message to the client. The Client chooses one of the OFFER messages for configuration, and responds with a broadcast REQUEST, thereby informing the Server that the OFFER message was acceptable. The Server commits the binding of the Client and its IP Address to persistent storage and responds with an acknowledgement message. The Client commits the IP address and configuration parameters, which includes lease time.
The pool is configured under server-profile-mode and server-profile-class-sub-mode. Class-based pool selection is always given priority over profile pool selection.
For more information about the DHCPv4 Server feature, see the Implementing the Dynamic Host Configuration Protocol module in the Cisco ASR 9000 Series Aggregation Services Router IP Addresses and Services Configuration Guide. For complete command reference of the DHCP commands, see the DHCP Commands chapter in the Cisco ASR 9000 Series Aggregation Services Router IP Addresses and Services Command Reference.
IPv6 ACL Based Forwarding Object Tracking
The IPv6 ACL based forwarding (ABF) object tracking feature enables ABF to decide which next hop address to use, based on the state of the object being tracked for the next hop. IPv6 SLA echos are used to determine reachability to the next hop address. If the primary route is unreachable, the secondary route is used to forward traffic. IPv6 ABF object tracking is supported on ASR 9000 Enhanced Ethernet line cards only.
For more information about the IPv6 ACL Based Forwarding Object Tracking feature, see the Implementing Access Lists and Prefix Lists module in the Cisco ASR 9000 Series Aggregation Services Router IP Addresses and Services Configuration Guide. For complete command reference of the access list commands, see the Access List Commands chapter in the Cisco ASR 9000 Series Aggregation Services Router IP Addresses and Services Command Reference.
Set DF Bit
The Set DF Bit feature enables to apply 'set df (do not fragment)' policy to an interface. Any packet that matches with the set df policy will either clear the bit or set the bit.
The set df bit policy can be enabled to clear the df bit before forwarding the packet in IPv4 traffic.
For more information on Set DF Bit, see the Implementing MPLS Traffic Engineering chapter in the Cisco ASR 9000 Series Aggregation Services Router MPLS Configuration Guide. For more information on Set DF Bit commands, see the MPLS Traffic Engineering Commands chapter in the Cisco ASR 9000 Series Aggregation Services Router MPLS Command Reference.
MPLS over IRB
The Integrated Routing and Bridging (IRB) feature in Cisco IOS XR Software enables routing of a given protocol between routed interfaces and bridge groups within a single router. IRB support for MPLS introduces these capabilities:
- Bridge-Group Virtual Interface (BVI) support under MPLS LDP
- Targeted LDP session to BVI neighbor
- MPLS OAM for BVI interfaces
- Netflow for BVI interfaces while MPLS is enabled
- L2VPN using targeted MPLS LDP to BVI destination
- L3VPN
- 6PE/6VPE
MPLS over IRB is supported completely on ASR 9000 Enhanced Ethernet Line Card and Cisco ASR 9001. MPLS over IRB is not supported on ASR 9000 Ethernet Line Card.
For more information on MPLS over IRB, see the Implementing MPLS Label Distribution Protocol chapter in the Cisco ASR 9000 Series Aggregation Services Router MPLS Configuration Guide. For more information on MPLS over IRB commands, see the MPLS Label Distribution Protocol Commands chapter in the Cisco ASR 9000 Series Aggregation Services Router MPLS Command Reference.
P2MP-TE Auto-tunnels
The MPLS point-to-multi point traffic-engineering auto-tunnels (P2MP-TE Auto-tunnels) feature enables dynamic creation and management of P2MP auto-tunnels for the transport of VPLS traffic on Cisco IOS XR Software. The P2MP-TE auto-tunnel configuration is disabled by default. Use the auto-tunnel p2mp-te tunnel-id configuration to enable P2MP-TE Auto-tunnel. This configures the tunnel ID range that can be allocated to P2MP auto-tunnels. This also determines the maximum number of P2MP auto-tunnels that can be created.
For more information on P2MP_TE Auto-tunnels, see the Implementing MPLS Traffic Engineering chapter in the Cisco ASR 9000 Series Aggregation Services Router MPLS Configuration Guide. For more information on Set DF Bit commands, see the MPLS Traffic Engineering Commands chapter in the Cisco ASR 9000 Series Aggregation Services Router MPLS Command Reference.
16 Queues Support
The ASR 9000 traffic manager (TM) for the enhanced Ethernet line cards now supports up to 16 Queues. The extension is from 8 queues to 16 queues at leaf level called L4 in a QoS policy.
The L3, L4 service profiles in 16 Q-mode are similar to that of the 8 Q-mode, with just an increase in the number of normal priority queues.
For more information on 16 Queues Support, see Cisco ASR 9000 Series Aggregation Services Router Modular Quality of Service Configuration Guide.
4arg
4arg is Cisco’s implementation of Object Size Checking (OSC). OSC is a useful static analysis utility and a critical runtime defense for the detection and prevention of buffer overflows. 4arg captures buffer overflows (at runtime) that are otherwise undetected by code analysis tools and human review. 4arg also carries a reporting and logging component.
4arg refers to a theoretical fourth argument to a string copy function representing the destination buffer size.
Session MIB support on subscriber sessions
SNMP monitoring requires information about subscribers of all types. The CISCO-SUBSCRIBER-SESSION-MIB is defined to model per-subscriber data as well as aggregate subscriber (PPPoE) data. It is required to support notifications (traps) for aggregate session counts crossing configured thresholds. Generic MIB Data Collector Manager (DCM) support for CISCO-SUBSCRIBER-SESSION-MIB, helps faster data collection and also better handling of parallel data.
Implementing Traffic Storm Control under a VPLS Bridge
Traffic storm control provides Layer 2 port security under a Virtual Private LAN Services (VPLS) bridge by preventing excess traffic from disrupting the bridge. This module describes how to implement traffic storm control.
Traffic storm control can be configured at the bridge domain level. Support has been added to allow storm control rate to be configured in kbps. For more information about the Traffic Storm Control feature, see the Implementing Traffic Storm Control under a VPLS Bridge module in the Cisco ASR 9000 Series Aggregation Services Router System Security Configuration Guide. For complete command reference of Traffic Storm Control commands, see the Traffic Storm Control Commands chapter in the Cisco ASR 9000 Series Aggregation Services Router System Security Command Reference.

Troubleshooting
Resolving Upgrade File Issues
NoteIn some very rare cases inconsistencies in the content of the internal configuration files can appear. In such situations, to avoid configuration loss during upgrade, the following steps can be optionally done before activating packages:
- Clear the NVGEN cache:
RP/0/RSP0/CPU0:router# run nvgen -F 1- Create a dummy config commit:
RP/0/RSP0/CPU0:router# config RP/0/RSP0/CPU0:router(config)# hostname <hostname> RP/0/RSP0/CPU0:rotuer(config)# commit RP/0/RSP0/CPU0:router(config)# end- Force a commit update by using the reload command. Press n when the confirmation prompt appears:
RP/0/RSP0/CPU0:router# reload Updating Commit Database. Please wait...[OK] Proceed with reload? [confirm]- Press n
In some cases other activity may preclude a reload. The following message may display:
RP/0/RSP0/CPU0:router# reload Preparing system for backup. This may take a few minutes ............System configuration backup in progress [Retry later]If you receive this message wait and then retry the command after some time.
