RIP Configuration

Routing Information Protocol

 Routing Information Protocol (RIP) is one of the oldest distance vector routing protocols, which employs 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 the source to a destination.
