Implementing OSPF Protocol in Cisco 2800 Series Router
The routing information protocol is a distance vector protocol, 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. The maximum number of hops allowed for RIP is 15. Originally each RIP router transmits full updates every 30 seconds. As the network grew in size, however, it became evident there could be a massive time. In most current networking environments, RIP is not the preferred choice for routing as its time to converge and scalability is poor compared to EIRGP and OSPF, because RIP based on distance vector routing protocol, But OSPF based on link state routing protocol.
