Chapter 37 IPv6 over MPLS: 6PE and 6VPE

Supported Features

In the MPLS-VPN model a VPN is defined as a collection of sites sharing a common routing table. A customer site is connected to the service provider network by one or more interfaces, where the service provider associates each interface with a VPN routing table–known as the VRF table.

Figure 37-2illustrates an MPLS VPN network.

Supported Features

The following 6PE and 6VPE features are supported on the Cisco ASR 901 router effective with Cisco IOS Release 15.2(2) SNI:

•IPv6 VRF support – Enabled for supporting 6VPE

•MPLS VPN 6VPE and 6PE – Provides IPV6 reachability for IPv6 edge routers across an MPLS network backbone running an IPv4 control plane, without making changes to the software on the MPLS P routers.

•6VPE and 6PE with QoS – Supports QoS provisioning in 6PE and 6VPE networks by using existing QoS infrastructure and configuration.

•MPLS VPN - VRF command for IPv4 and IPv6 VPN – Supports commands that allows users to enable IPv4 and IPv6 in the same VRF.

Note All the above features are built upon existing IPv4, IPv6, MPLS and BGP infrastructure in the IOS and Cisco ASR 901 data plane support.
