Routing information protocol The routing information protocol (‘rip’) is one of the oldest distance-vector routing protocols which employ the hop count as a routing metric. Rip prevents routing loops by implementing a limit on the number of hops allowed in a path from source to destination. Routing information protocol (rip) is a Read more…
