Cisco router RIP Protocol and IGRP Protocol configuration (1)

RIP and IGRP are commonly used router configuration protocols. What problems should we pay attention to when configuring RIP and IGRP? What should we do? The following configuration steps provide detailed answers.

RIP Protocol

RIP (Routing information Protocol) is an Internal Gateway Protocol (IGP) that is widely used earlier and is suitable for small-sized similar networks, is a typical distance-vector protocol. For more information, see RFC1058 and RFC1723.

RIP broadcasts UDP packets to exchange route information and sends route information updates every 30 seconds. RIP provides the hop count (hop count) as a scale to measure the route distance. The hop count is the number of Cisco routers that a packet must pass to the target. If there are two Cisco routers with different speeds or bandwidths to the same destination, but the hop count is the same, RIP considers the two routes to be at an equal distance. The maximum number of hops supported by RIP is 15, that is, the maximum number of Cisco routers to pass between the source and destination networks is 15, and the number of hops is 16, which indicates that it is not reachable.
