Configure VRF Interfaces on PE Routers for Each VPN Customer
After a VRF instance is created, you must associate that VRF instance with an interface or a sub-interface on
the PE routers.
You must remove the IPv4 or IPv6 addresses from an interface prior to assigning, removing, or changing an
interface's VRF. If this is not done in advance, any attempt to change the VRF on an IP interface is rejected.
Note
Configuration Example
This example assigns an IP address 192.13.26.6 to the interface (HundredGigE0/0/1/0.1601) on PE1 router
and associates the VRF instance vrf1601, to that interface.
Router-PE1#configure
Router-PE1(config)#interface HundredGigE0/0/1/0.1601
Router-PE1(config-if)#vrf vrf1601
Router-PE1(config-if)#ipv4 address 192.13.26.6 255.255.255.252
Router-PE1(config-if)#encapsulation dot1q 1601
Router-PE1(config)#commit
