What is a typical use case for redistribution between RIP and OSPF in a multi-vendor network?

• A. To translate OSPF routes into RIP for compatibility on legacy devices only.
• B. To forcibly convert all OSPF into RIP to simplify routing.
• C. Integrating legacy RIP domains into an OSPF backbone or mixing vendors while maintaining routing coherence.
• D. To avoid route loops by suppressing all external routes.

Answer: (C)

Redistribution between RIP and OSPF is about making two different routing worlds work together. In a multi-vendor network you often have some parts running legacy RIP and others using OSPF. The practical use case is to integrate those RIP domains into the OSPF backbone so every part of the network can reach every destination, while keeping routing coherent across devices from different vendors. With redistribution, border routers selectively inject routes from one protocol into the other, and you can tune metrics and use route tagging to prevent loops and avoid instability. This arrangement is a common way to extend modern routing into older or diverse segments, rather than trying to convert everything to a single protocol or suppressing external routes.
