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.
