RIP and route redistribution

Redistribution imports routes from one protocol to another. Redistribution sends route updates for a protocol-based route through another protocol. For example, if RIP routes exist in a router and they must travel through a BGP network, configure redistribution of RIP routes through BGP. Redistribution sends RIP routes to a router that uses BGP.

You can redistribute routes

To configure interface-based redistribution, configure a route policy, and then apply it to the interface. Configure the match parameter to the protocol from which to learn routes.

You can redistribute routes on a global basis, rather than for every interface. The switch adds support for global RIP redistribution. Use the ip rip redistribute command to accomplish the (intraVRF) redistribution of routes through RIP, so that RIP redistribution occurs globally on all RIP-enabled interfaces. This redistribution does not require a route policy, but you can use one for more control.

If you configure redistribution globally and on an interface, redistribution through the route policy takes precedence.

You can redistribute routes from a protocol in one VRF to RIP in another VRF. You can use a route policy for redistribution control. If you enable route redistribution between VRF instances, ensure that IP addresses do not overlap.
