Clearing Dynamic RIP Interfaces

You can use the clear ip rip dynamic-interfaces to clear any existing dynamic RIP interfaces that were created by the ip rip copy-to-dynamic command. If the router is still using the ip rip copy-to-dynamic command, when the router recreates the dynamic interfaces, they use the RIP attributes from the interface to which they refer. If the router no longer uses the ip rip copy-to-dynamic command, any newly created dynamic interfaces do not use the RIP attributes from the reference interface.
