This guide provides configuration information for features that are platform-specific to the Cisco 10000 series router. Documentation is also provided for cross-platform features that function differently on the Cisco 10000 series router than on other supported platforms.

Cross-platform features that function on the Cisco 10000 series router as they do on other supported platforms, and platform-independent features that are supported on the Cisco 10000 series router are described in the general Cisco IOS documentation.

This introduction provides information about the following topics:

This guide is designed for system and network managers responsible for configuring broadband aggregation, leased-line, and MPLS services and on the Cisco 10000 series router. The manager should be experienced using Cisco IOS software and be familiar with the operation of the Cisco 10000 series router.

Document Organization

This guide contains the following chapters:

Chapter	Title	Description
Chapter 1	Broadband Aggregation Overview	Lists new features and enhancements in each release; describes hardware requirements. Provides examples of broadband and leased-line architecture models.
Chapter 2	Scalability and Performance	Describes limitations and restrictions, and how to configure the Cisco 10000 series router for high scalability.
Chapter 3	Configuring Remote Access to MPLS VPN	Describes the Remote Access (RA) to MPLS VPN feature that allows the service provider to offer a scalable end-to-end VPN service to remote users.
Chapter 4	Configuring Multiprotocol Label Switching	Describes MPLS-related features, such as BGP Multipath load sharing, Session Limit per VRF, and Half-duplex VRF.
Chapter 5	Configuring Layer 2 Tunnel Protocol Access Concentrator and Network Server	Describes how to configure the Cisco 10000 series router as a Layer 2 Tunnel Protocol Access Concentrator (LAC) or as an L2TP Network Server (LNS). The managed LNS feature of the Cisco 10000 series router enables the router to assign a subscriber session to a VRF instance and route the session within the VRF to the destination network.
Chapter 6	Configuring PPPoE over Ethernet and IEEE 802.1Q VLANs	Describes the PPPoE over Ethernet feature that enables direct connection to an Ethernet interface. Also describes the IEEE 802.1Q VLANs feature that enables the Cisco 10000 series router to support PPPoE over IEEE 802.1Q encapsulated VLANs using Gigabit Ethernet.
Chapter 7	Configuring IP Unnumbered over VLAN	Describes the IP Unnumbered over VLAN feature that helps service providers to conserve IP address space for service provider configurations that include Ethernet VLAN subinterfaces.
Chapter 8	Configuring ATM Permanent Virtual Circuit Autoprovisioning	Describes how to configure the ATM PVC autoprovisioning feature that enables DSL wholesale service providers to dynamically provision ATM service for subscribers using a local configuration. Also describes the VBR-nrt Oversubscription feature.
Chapter 9	Configuring the Multihop Feature	Describes how to configure the multihop feature that enables the Cisco 10000 series router to terminate sessions arriving in L2TP tunnels from LACs and to forward the sessions through new L2TP tunnels to the router's peer L2TP Network Server (LNS). Also describes how to configure the preservation of the IP type of service (ToS) field for tunneled IP packets.
Chapter 10	Configuring Address Pools	Describes address assignment mechanisms, including the on-demand address pool manager feature and the overlapping addresses feature. Describes how to configure each of these features.
Chapter 11	Configuring Local AAA Server, User Database—Domain to VRF	Describes the Local AAA Server, User Database—Domain to VRF feature, which extends the Cisco IOS AAA Authorization to local AAA profiles on the router without using an AAA Server.
Chapter 12	Configuring Traffic Filtering	Describes the IP Receive ACLs and Time-Based ACLs features that provide filtering capability for traffic that is destined for the router and protects the router from remote intrusions.
Chapter 13	Unicast Reverse Path Forwarding	Describes the Unicast Reverse Path Forwarding feature that verifies if the path of an incoming packet is consistent with the local packet forwarding information. The validity of this path determines whether uRPF passes or drops the packet.
Chapter 14	Configuring Automatic Protection Switching	Describes the Multirouter Automatic Protection Switching (MR-APS) feature that enables SONET connections to switch from one SONET circuit to another SONET circuit if a circuit failure occurs.
Chapter 15	Configuring IP Multicast	Describes the IP Multicast feature.
Chapter 16	Configuring RADIUS Features	Describes the RADIUS attribute screening, RADIUS transmit retries, RADIUS Attribute 31: PPPoX Calling-Station-ID, and RADIUS packet of disconnect features.

Chapter 20	Configuring Gigabit EtherChannel Features	Describes Gigabit EtherChannel features available on Cisco 10000 series router.
Chapter 21	Configuring IP Version 6	Lists the IPv6 features that are supported on the Cisco 10000 series router and notes limitations of that support.
Chapter 22	Configuring Template ACLs	Describes Template ACLs, in which one ACL represents many similar ACLs.
Chapter 23	Protecting the Router from DoS Attacks	Describes how to protect against denial of service (DoS) attacks.
Chapter 24	IP Tunneling	Describes the Generic Routing Encapsulation Tunnel IP Source and Destination VRF Membership feature.
Appendix A	RADIUS Attributes	Lists RADIUS attributes that the Cisco 10000 series router supports.
