Route leaking 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
