Route leaking using route maps You can leak routes in one VRF instance to another VRF instance using route maps. To leak routes in one VRF instance using route maps: 1. Enter the VRF from which you want to leak routes using route targets. CONFIGURATION ip vrf source-vrf-name ip vrf VRF-A 2. Configure the IP prefix. CONFIGURATION ip prefix-list prefix-list-name {permit | deny} ip-address ip prefix-list abc permit 20.0.0.0/24 or ip prefix-list abc deny 20.0.0.0/24 3. Configure the route-map. CONFIGURATION route-map route-map-name route-map xyz 4. Associate the prefix list to the route-map. CONFIGURATION route-map route-map-name {permit | deny} rule match ip address prefix-list prefix-list-name route-map xyz permit 10 match ip address prefix-list abc or route-map xyz deny 10 match ip address prefix-list abc 5. Export the routes from a VRF instance using route maps. VRF CONFIGURATION ip route-export route-target route-map-name route-map-name ip route-export 1:1 route-map xyz 6. Enter the destination VRf instance into which you want to leak the routes using route maps. CONFIGURATION ip vrf destination-vrf-name ip vrf VRF-B 7. Import these leaked routes into another VRF instance. VRF CONFIGURATION ip route-import route-target ip route-import 1:1 OS10(config)#interface ethernet 1/1/1 OS10(conf-if-eth1/1/1)# ip vrf forwarding VRF1 OS10(conf-if-eth1/1/1)# ip address 120.0.0.1/24 OS10(config)#interface ethernet 1/1/2 OS10(conf-if-eth1/1/2)# ip vrf forwarding VRF2 OS10(conf-if-eth1/1/2)# ip address 140.0.0.1/24 522 Layer 3
