I would think it would depend on the complexity of the network and how the network advertises routes to peer networks. I'm always in favor the simpler the better but with RIP you do lose the ability to use variable bit masks (CIDR) and faster routing algorithms like DUAL used in Cisco routers and I'm not a big fan of OSPF.

One very interesting discussion was surrounding RIP and its use versus a protocol like OSPF. It seems that many Network Engineers consider RIP an old antiquated protocol that should be thrown in back of a closet "never to be seen or heard from again". Some even preferred using a more complex protocol like OSPF instead of RIP. I am of the opinion that every protocol has its place, which seems to be contrary to some engineers way of thinking. This leads to my question. What are your views of when and where the RIP protocol is useful? Please excuse me if this is the incorrect forum for such questions. -- Jesse Loggins CCIE#14661 (R&S, Service Provider)
