Overview
RIP is an interior gateway protocol (IGP) typically used in small, homogeneous
networks. RIP uses distance-vector routing to route information through IP networks.
Distance-vector routing requires that each router simply inform its neighbors of its
routing table. For each network path, the receiving router picks the neighbor
advertising the lowest metric, then adds this entry into its routing table for
readvertisement.
Any host that uses RIP is assumed to have interfaces to one or more networks. These
networks are considered to be directly connected networks. RIP relies on access to
certain information about each of these networks. The most important information
is the network’s metric
.
RIP Metric
RIP uses the hop count as the metric (also known as cost) to compare the value of
different routes. The hop count is the number of routers that data packets must
traverse between RIP networks. Metrics range from 0 for a directly connected network
