Routing Information Protocol (RIP)
A distance-vector model based on RIP concepts, not a full protocol implementation.
  • RIP uses hop count as its sole routing metric. Every link between routers has a cost of 1 hop.
  • The simulator applies distance-vector updates: routers share their simulated routing tables with adjacent routers. It animates those updates instead of sending RIP packets.
  • A router compares each neighbor's advertised distance plus the link cost with its current route, accepting better alternatives and changed costs from the current next hop.
  • RIP has a maximum hop count of 15. Any route with a cost of 16 is considered infinite, marking that destination as unreachable.
  • The demo stops after several unchanged update rounds. This is a simulator stopping rule, not a guarantee about real RIP timers or convergence.
  • After a link failure, routes can count to infinity as neighbors advertise stale information. This model does not implement split horizon or route poisoning.
  • Use Case: Best suited for small, simple networks where simplicity is more important than fast convergence or optimal path selection.
