  3. What is RIP? RIP is a dynamic routing protocol used in local and wide area networks. As such it is classified as an interior gateway protocol (IGP). It uses the distance-vector routing algorithm. It was first defined in RFC 1058 (1988). The protocol has since been extended several times, resulting in RIP Version 2 (RFC 2453). Both versions are still in use today, however, they are considered to have been made technically obsolete by more advanced techniques such as Open Shortest Path First (OSPF) and the OSI protocol IS-IS. RIP has also been adapted for use in IPv6 networks, a standard known as RIPng (RIP next generation)protocol, published in RFC 2080 (1997).

  4. History of RIP The routing algorithm used in RIP, the Bellman-Ford algorithm, was first deployed in a computer network in 1967, as the initial routing algorithm of the ARPANET. The earliest version of the specific protocol that became RIP was the Gateway Information Protocol, part of the PARC Universal Packet internetworking protocol suite, developed at Xerox Parc. A later version, named the Routing Information Protocol, was part of Xerox Network Systems. A version of RIP which supported the Internet Protocol (IP) was later included in the Berkeley Software Distribution (BSD) of the Unix operating system. It was known as the routed daemon. Various other vendors would create their own implementations of the routing protocol. Eventually, RFC 1058 unified the various implementations under a single standard.
