Limitations • In VLT scenarios, the resolved ARP entry for the leaked route is not synchronized between the VLT peers. The ARP entry resolved in the source VRF is programmed into the leaked VRF when the leaked route configuration is active. • During downgrade from 10.4.2, the leaked route configuration is restored. However, the routes remain inactive in the destination VRF instance. • During downgrade from 10.4.2, the update-source-if command is not restored. 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 Codes: C - connected S - static B - BGP, IN - internal BGP, EX - external BGP O - OSPF, IA - OSPF inter area, N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2, E1 - OSPF external type 1, E2 - OSPF external type 2, * - candidate default, + - summary route, > - non-active route Gateway of last resort is not set Destination Gateway Dist/Metric Last Change C 120.0.0.0/24 via 120.0.0.1 ethernet1/1/1 0/0 00:00:57 S 140.0.0.0/24 Direct,VRF2 ethernet1/1/2 1/0 00:00:04 OS10(config)# do show ip route vrf VRF2 Codes: C - connected S - static B - BGP, IN - internal BGP, EX - external BGP Layer 3 483
