Overview of Routing Information Protocol (RIP)

- Routing information protocol, or RIP,…is a true distance vector routing protocol.…RIP sends a complete routing table out…all active interfaces every 30 seconds.…It relies on hop count as a metric to determine…the best path to a remote network, but it has a maximum…allowable hop count of 15 by default.…So a destination of 16 hops would be considered unreachable.…RIP works okay in very small networks,…but it's inefficient on large networks with slow WAN…links or on networks with a large number of routers…installed.…

It's completely useless on networks that have links…with variable bandwidths.…RIP doesn't even look at the bandwidth.…RIP version one uses only classful routing,…which means that all devices in the network…must use the same subnet mask.…This is because RIP version one doesn't send updates…with subnet mask information in tow.…RIP version two, however, provides something called…prefix routing and does send subnet mask information…with its route updates.…This is called classless routing.…To configure RIP routing, just turn on the protocol…
