Routing information protocol
It is a dynamic routing protocol used in local and wide area networks.
A router in the network needs to be able to look at a packetâ„¢s destination address and then
determine which of the output ports is the best choice to get the packet to that address.it
is classified as an interior gateway protocol (IGP) and uses the distance vector algorithm.
RIP has also been adapted for use in IPv6 networks in the RIPng form.
Technical details
distance-vector routing protocol, which employs the hop count as a routing metric. routing
loops is prevented heer by implementing a limit on the number of hops allowed in a path. The
hold down time is 180 seconds. RIP router transmitted full updates every 30 seconds. Thus
there could be a massive traffic burst every 30 seconds,as the networks grew in size and
number. deliberate variation into the update timer intervals is introduced for each router.
RIP version 1:
It uses classful routing. The periodic routing updates do not carry subnet information. all
subnets in a network class must have the same size.
RIP version 2:
RIP version 2 (RIPv2) was developed in 1993 due to the deficiencies in RIP version 1. It
could carry subnet information, thus supporting Classless Inter-Domain Routing (CIDR).hop
count limit of 15 was maintained as such. RIPv2 multicasts the entire routing table to all
adjacent routers
RIPng(RIP next generation):
It has Support of IPv6 networking.RIPng does not allow the attaching arbitrary tags to
routes. It equires specific encoding of the next hop for a set of route entries.
