Visit: https://routing.toolsforteaching.co.uk/ FREE to use.

The Network Routing Simulator is an interactive, browser-based teaching tool that animates how RIP and OSPF route packets across a realistic multi-router LAN/WAN network.

What Students Learn

  • Distance Vector vs Link State — how each protocol type builds its view of the network
  • Bellman-Ford algorithm (RIP) — distributed hop-count convergence
  • Dijkstra’s SPF algorithm (OSPF) — shortest path calculation
  • OSPF cost formula — Cost = 10⁸ ÷ Bandwidth
  • Convergence phases — Hello, DBD, LSR/LSU/LSAck, LSA flooding, SPF calculation
