  • Page 45: About Rip Routing Updates

    About RIP Routing Updates Introduction RIP defines a method for propagating routing information among routers. It provides IP software with the information needed to make intelligent routing decisions. The information, passed in RIP updates packets from router-to-router, consists of two items, a network ID and a hop count.
  • Page 46 regarded R2 as an alternate path to Net 1. The second is called “poison reverse,” which stipulates that routes are advertised as unreachable on the interface on which the route is learned. Had poison reverse been used in the preceding example, R2 would have advertised Net 1 as unreachable in its RIP updates to R1.
