Foil 29 Routing Information Protocol (2)

From Introduction to Network Security Lectures at Xi'an Jaotong University -- Sept 1998. by Roman Markowski


1 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
