Configuring static route leaking

To configure static route leaking:
  1. Enter the interface in the source VRF instance that contains the static routes that you want to leak.
    interface interface-name
    CONFIGURATION Mode
  2. In INTERFACE CONFIGURATION Mode, assign the interface to the source VRF instance.
    ip vrf forwarding vrf1
    INTERFACE CONFIGURATION Mode
  3. Assign an IP address to the interface.
    ip address ip-address
    VRF CONFIGURATION Mode
  4. Enter the interface of the VRF instance to which you want to leak the static routes.
    interface interface-name
    CONFIGURATION Mode
  5. In INTERFACE CONFIGURATION Mode, assign the interface to the destination VRF instance.
    ip vrf forwarding vrf2
    INTERFACE CONFIGURATION Mode
  6. Configure the static route that you want to leak on the destination VRF instance.
    ip route vrf dest-vrf-name route nexthop-interface
  7. Configure the static route that you have configured earlier in the source VRF instance to be available in the destination VRF instance also.
    ip route vrf src-vrf-name route nexthop-interface
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-eth1/1/1)# ip vrf forwarding VRF2
OS10(conf-if-eth1/1/1)# ip address 140.0.0.1/24
OS10(config)#ip route vrf VRF1 140.0.0.0/24 interface ethernet 1/1/2
OS10(config)#ip route vrf VRF2 120.0.0.0/24 interface ethernet 1/1/1

The following example shows the show output:
OS10(config)# do show ip route vrf VRF1
