In this Lab you will be using your troubleshooting skills to analyze a network that is using RIP as the routing protocol. The sales department has just been moved to a new location and connected to the company network via a frame-relay connection. After the move all the computers in the sales department can no longer access the company network. Your job is to find the cause of the failure and restore connectivity.
RIP Routing Protocol:
RIP is a distance-vector routing protocol, that employs the hop count as a routing metric. The hold down time is 180 seconds. 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. This hop limit, however, also limits the size of networks that RIP can support. A hop count of 16 is considered an infinite distance and used to deprecate inaccessible, inoperable, or otherwise undesirable routes in the selection process.
RIP implements the split horizon, route poisoning and holddown mechanisms to prevent incorrect routing information from being propagated.
