Question

An engineer redistributes OSPF routes into RIP on a border router with the command 'redistribute ospf 1' under the RIP process. After the change, none of the OSPF-learned prefixes appear in the RIP database of neighboring routers, although the OSPF routes are present in the border router's own routing table. The RIP adjacency and interfaces are otherwise healthy. What is the most likely cause?

Accepted Answer

RIP requires a seed metric that was not supplied, so the redistributed routes are assigned an infinite (16) metric and are not advertised.

Answer

OSPF external routes cannot be redistributed into RIP without first tagging them with a route map.

Answer

The 'redistribute ospf 1' command must include the 'subnets' keyword to redistribute classless OSPF prefixes into RIP.

Answer

RIP automatically summarizes the redistributed routes to their classful boundary, hiding the individual prefixes.
