Appendix B. RIP (Routing Information Protocol)

This appendix covers the following topics:

• RIP Routing Table

• RIP Routing Convergence

• RIP Concerns

• RIP Routing Protocol Summary

RIP is a simple distance-vector routing protocol, and because RIP is an open standard, it is a safe presumption that any network routing device is capable of supporting RIP. RIP is an Interior Gateway Protocol (IGP) and is designed for use in small, simple networks. RIP was designed and engineered to support only Classful Routing and has no support for Classless Routing, such as CIDR (Classless Inter-Domain Routing).
