NOTE: For end-to-end traffic to flow, you must specify the source for self-originating packets and leak the same into the destination VRF. To mitigate this issue and have control over the source IP address for leaked routes, you can create a loopback interface and associate it with the leaked VRF. To explicitly mention the source interface for the leaked VRF: Enter the following command: update-source-if VRF CONFIGURATION Mode After you configure the source IP address in a leaked VRF, if ping is initiated without -I option, then the source IP address will be that of the loopback interface. Route leaking using route targets You can leak routes in one VRF instance to another using route targets. NOTE: You can leak routes using route targets only on the default and non-default VRF instance. You cannot leak routes using route targets on the management VRF instance. To leak routes in one VRF instance using route targets: 1. Enter the VRF from which you want to leak routes using route targets. CONFIGURATION ip vrf source-vrf-name 2. Export the route that belongs to one VRF instance. VRF CONFIGURATION ip route-export 1::1 3. Enter the non-default VRF instance to which you want to leak the route. CONFIGURATION ip vrf destination-vrf-name ip route-import 1::1 The routes that you exported from the source VRF instance are now available in the destination VRF instance. NOTE: When you configure static route leaking, only a single ECMP route- the best ECMP route - leaks to another VRF instance. The other ECMP static routes are not leaked to the other VRF instances. 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 484 Layer 3
