How to Configure IPv6 over MPLS: 6PE and 6VPE

Configuring 6VPE

6VPE requires setting up of IPv6 connectivity from PE to CE routers, MP-BGP peering to the neighboring PE and MPLS/IPv4 connectivity to the core network using supported routing protocols (like OSPF, IS-IS, EIGRP, Static) as done in 6PE. In addition, IPv6 VRFs have to be created on the PE routers and attached to the interfaces connecting to CE routers. IPv6-only or dual-stack(multi-protocol) VRFs support IPv6 VRF definitions.

To configure 6VPE, perform the tasks given below:

•Setting up IPv6 Connectivity from PE to CE Routers

•Setting up MP-BGP Peering to the Neighboring PE

•Setting up MPLS/IPv4 Connectivity with LDP

•Creating IPv6 VRFs on PE Routers

Setting up IPv6 Connectivity from PE to CE Routers

To configure IPv6 connectivity from PE to CE routers, complete the following steps:

SUMMARY STEPS

1.enable

2.configure terminal

3.router bgp as-number

4.address-family ipv6 [vrf vrf-name]

5.neighbor {ip-address ipv6-address peer-group-name}remote-asas-number

6.neighbor {ip-address ipv6-address peer-group-name}activate

7.exit-address-family

DETAILED STEPS

	Command		Purpose
Step 1	enable		Enables privileged EXEC mode.
			• Enter your password if prompted.
	Example:
	Router> enable
Step 2	configure terminal		Enters global configuration mode.
	Example:
	Router# configure terminal
Step 3	router bgp as-number		Enters the number that identifies the autonomous system (AS) in
			which the router resides.
	Example:		• as-number—Autonomous system number. Range for 2-byte
	Router(config)# router bgp 100		numbers is 1 to 65535. Range for 4-byte numbers is 1.0 to
			65535.65535.
