Simple VRF-lite configuration examples
Dynamic inter-VRF communication with RIP routing to external peers
The partial configuration example below shows the key components required to support dynamic inter-VRF communication between two VRF instances using BGP, with RIP routing to external peers.
RIP address-families are created, and each RIP address-family is associated with a VRF instance. To achieve inter-VRF communications, BGP is redistributed into each RIP family. Conversely, BGP address-families are created and each BGP address-family is associated with a VRF instance, and RIP is redistributed into each BGP address-family. Connected routes are also redistributed into BGP to be leaked between VRF instances.
