RIP uses Bellman-For algorithm currently RIP IPv4 has two versions, RIPv1 and RIPv2.
RIP has the following main features:
RIP is a typical distance vector routing protocol.
RIP messages sent by the broadcast address 255.255.255.255, RIPv2 send messages
by using multicast address 224.0.0.9, both using the port 520 of UDP
RIP takes the minimum hop count to the destination network as the routing metric,
rather than the bandwidth and delay of the link.
RIP is designed for small networks. The number of hops is limited to 15 hops, and
the 16 hop is not reachable.
RIP-1 is a kind of class routing protocol, does not supporting discontinuous subnet
design.
RIP-2 support CIDR and VLSM variable subnet mask, which make it supports the
discontinuous subnet mask design
RIP periodic full routing updating, make the routing table broadcast to the neighbor
router, broadcast cycle default 30 seconds.
RIP protocol management distance is 120.
For small networks, in terms of occupied bandwidth, RIP is small cost and easy to
configure, manage, and implement, and RIP is still in use. But RIP also has obvious
shortcomings. When there is more than one network will appear loop problem. In order
to solve the loop problem, IETF proposed a split-Horizon method, the routing
information received at this interface will no longer go out from the interface. The scope
of the division solves the routing loop problem between two routers, but can’t prevent
the problem which is the loop mainly formed by delay factor because of large scale
network. The trigger update requires the router to transmit its routing table immediately
when the link changes. These speeds up the convergence of the network, but prone to
broadcast flooding. In short, the solution of the loop problem needs to consume a certain
amount of time and bandwidth. If the RIP protocol is adopted, the number of links in the
network can’t exceed 15, which makes the RIP protocol is not suitable for large networks.
RIP Working principle
RIP is a distributed type routing protocol based on distance vector, which is the
standard protocol of the Internet. Its biggest advantage is simple. The RIP protocol
requires that each router in the network maintain a distance record from itself to each
other destination network. The RIP protocol defines “distance” as: the distance of a router
directly connected network defines as 1.the distance of a router not directly connected
network defines as pass each router plus 1. “Distance” is also called “hops”. RIP allows
one path contain up to 15 routers, so distance equal to 16 is unreachable. So RIP protocol
only applies to small Internet.
RIP 2 comes from RIP and is a supplementary protocol for RIP. It is mainly used to
increase the number of loaded useful information and increase its security performance.
RIPv1 and RIPv2 are UDP-based protocols. Under RIP2, each host or router sends and
