Enabling RIP on Dynamic IP Interfaces

You can use the ip rip copy-to-dynamic command to enable RIP on dynamic, unnumbered IP interfaces. This command allows the dynamic interfaces, as they are created, to copy RIP settings from a numbered IP interface to which the interfaces refer for their source address.

Caution: RIP transmits a complete set of routing updates at each update interval. This can result in a very large number of RIP updates. When configuring RIP over dynamic interfaces, we strongly recommend that you configure an output policy on the reference interface to limit the amount of routing information that RIP transmits to each peer.
