RIP (Routing Information Protocol)

A distance-vector routing protocol that employs the hop

count metric for selecting the shortest path between an originating and a destination router. Each router in a network builds a database of the other routers to which it connects, and advertises that database to its neighboring routers every 30 seconds (RIP is very chatty), or when topology changes occur. Based on that information, the originating router selects the path with the lowest hop count. RIP is an Interior Gateway Protocol (IGP) used to exchange path information between routers in the same network domain.The initial RIPv1 was specified by the Internet Engineering Task Force (IETF) in RFC 1058, RIPv2 in RFC

2453, and RFCng for IPv6 in RFC 2080. RIP maps into Layer 3, the Network Layer of the OSI Reference Model, and can operate over heterogeneous networks. See also domain, hop, IGP, Network Layer, and OSI Reference Model.
