Configuring IPv6 VRF-lite

Beginning with Release IOS XE 3.5.0E and IOS 15.2(1)E, to support IPv6 VRF-lite, we transition from
the ip vrf command to the "new" vrf definition command.
Configure VRFs
To configure one or more VRFs, perform this task:
Command
Switch# configure terminal
Step 1
Switch(config)# ipv6 routing
Step 2
Switch(config)# vrf definition
Step 3
vrf-name
Switch(config-vrf)# address-family
Step 4
ipv4 | ipv6
Switch(config-vrf)# rd
Step 5
route-distinguisher
Switch(config-vrf)# route-target
Step 6
{
export
route-target-ext-community
Switch(config-vrf)# import map
Step 7
route-map
Switch(config-vrf)# interface
Step 8
interface-id
Switch(config-if)# ip vrf forwarding
Step 9
vrf-name
Switch(config-if)# end
Step 10

Purpose
Enters global configuration mode.
Enables IPv6 routing.
Names the VRF and enters VRF configuration mode.
(Optional) IPv4 by default. Configuration MUST for ipv6.
(Optional) Creates a VRF table by specifying a route
distinguisher. Enter either an Autonomous System number
and an arbitrary number (xxx:y) or an IP address and
arbitrary number (A.B.C.D:y).
(Optional) Creates a list of import, export, or import and
export route target communities for the specified VRF.
Enter either an AS system number and an arbitrary number
(xxx:y) or an IP address and an arbitrary number
(A.B.C.D:y).
This command is effective only if BGP is running.
Note
(Optional) Associates a route map with the VRF.
Enters interface configuration mode and specify the Layer
3 interface to be associated with the VRF. The interface
can be a routed port or SVI.
Associates the VRF with the Layer 3 interface.
Returns to privileged EXEC mode.
