Redistribute leaked routes from one VRF to another VRF
Use the following procedure to export (leak) and redistribute specific IPv4 routes from one VRF instance to another VRF
instance:
● Create a route map.
route-map route-map-name
Use any of the supported match or set attributes as required.
● Enter the VRF from which you want to leak routes in CONFIGURATION mode.
ip vrf source-vrf-name
● Export all routes that belong to one VRF instance in VRF-CONFIGURATION mode.
ip route-export route-target [route-map route-map-name]
Or
ipv6 route-export route-target [route-map route-map-name]
Use any of the supported match or set attributes as required.
●
Enter the VRF instance to which you want to leak routes in CONFIGURATION mode.
ip vrf destination-vrf-name]
● Import routes from another VRF instance in VRF-CONFIGURATION mode using the same route target.
ip route-import route-target [route-map route-map-name]
Or
ipv6 route-import route-target [route-map route-map-name]
Use any of the supported match or set attributes as required.
● Export routes from the second VRF instance to the first VRF instance in VRF-CONFIGURATION mode using a different
route target.
ip route-import route-target [route-map route-map-name]
Or
ipv6 route-import route-target [route-map route-map-name]
Use any of the supported match or set attributes as required.
● Import routes to the first VRF instance from the second VRF instance in VRF-CONFIGURATION mode using the same route
target that you use to export from the second VRF instance.
ip route-import route-target [route-map route-map-name]
Or
ipv6 route-import route-target [route-map route-map-name]
Use any of the supported match or set attributes as required.
● Redistribute leaked routes:
○ Redistribute leaked BGP routes in BGP-AF-CONFIGURATION mode.
redistribute imported-bgp-routes vrf source-vrf-name [route-map rmap-name]
○ Redistribute leaked OSPF routes in ROUTER-OSPF-CONFIGURATION mode.
redistribute imported-ospf-routes [route-map rmap-name]
