host1:vr1(config-vrf)#import map Another-route-map
host1:vr1(config-vrf)#export map A-route-map
host1:vr1(config-vrf)#exit
Assign interfaces for PE-to-CE links to the VRF from outside or inside the VRF context:
5.
host1:vr1(config)#interface gigabitEthernet 1/0
host1:vr1(config-if)#ip vrf forwarding vrfA
host1:vr1:vrfA(config-if)#ip address 10.16.2.77 255.255.255.0
host1:vr1:vrfA(config-if)#exit
or
host1:vr1(config)#virtual-router :vrfA
host1:vr1:vrfA(config)#interface gigabitEthernet 1/0
NOTE: You can also use the ip vrf forwarding command to specify secondary route
lookup at the parent (global) level, in the event the original lookup does not yield any
results.
Use either of the following methods to establish how the VRF learns routes to
6.
customer sites:
Create static routes to the customer site in the VRF by one of the following
methods:
host1(config)#virtual-router vr1
host1:vr1(config)#ip vrf vpnA
host1:vr1(config-vrf)#ip route vrf vrfA 10.3.0.0 255.255.0.0 10.1.1.1
host1:vr1(config-vrf)#ip route vrf vrfA 10.12.0.0 255.255.0.0 10.1.1.1
or
host1(config)#virtual-router vr1:vrfA
host1:vr1:vrfA(config)#ip route 10.3.0.0 255.255.0.0 10.1.1.1
host1:vr1:vrfA(config)#ip route 10.12.0.0 255.255.0.0 10.1.1.1
Configure an IGP on the VRF to learn routes from the CE router.
See "Configuring IGPs on the VRF" on page 437 for examples.
Configure a PE-to-CE EBGP session.
See "Configuring PE-to-CE BGP Sessions" on page 445 for information about
configuring EBGP.
(Optional) Configure the router to generate a label for each different FEC pointed
7.
to by a BGP route in the VPN.
host1:vr1(config-vrf)#ip mpls forwarding-mode label-switched
(Optional) For carrier-of-carriers VPNs, configure carrier-of-carriers mode in the
8.
provider carrier's PE router that connects to the customer carrier's network.
host1:vr1:VrfA(config)#mpls topology-driven-lsp
See "Carrier-of-Carriers IPv4 VPNs" on page 469 for information about configuring
carrier-of-carriers VPNs.
