Routing Information Protocol (2)
RIP Characteristics
- RIP sends routing-updates messages at regular intervals and when the network topology changes (updates to routing tables)
- RIP maintains only the best routes (with the lowest metric value)
- RIP uses a single routing metric (hop count) to measure a distance between a source and a destination) - the maximum number of hops is 15
- stability features: hold-down mechanism and split-horizon prevent incorrect routing information from being propagated
- routing timer default = 30 sec
