RFC 1058 specified an open standard RIP. This RIP, like its proprietary ancestors, was designed as a simple distance-vector routing protocol. It was specifically designed for use as an Interior Gateway Protocol (IGP) in small, simple networks.

RIP Packet Format

RIP uses a special packet to collect and share information about distances to known internetworked destinations. This packet contains the following structure:

  • A 1-octet command field

  • A 1-octet version number field
