  1. Routing Information Protocol (RIP)

  2. RIP Topics • RIP features and limitations • RIP v1 operation • RIP metric • RIP configuration

  3. RIP Features and Limitations • Features • Simplicity in configuration and operation • Standard, tested protocol • Version 2 overcomes some issues • Limitations • Slow convergence • Poor scalability • Route metric calculation is not granular

  4. RIP v1 Operation • Broadcasts periodic updates to neighbors • Update includes routes and metric for each route • Summarizes at classful boundaries • Receiving router adds routes with best metric to routing table

  5. RIP Metric 19.2 kbps T1 T1 • Hop count metric selects the path • Maximum hops is 15 • Hop count of 16 indicates unreachable T1

  6. RIP Timers • update 30 seconds • invalid 180 seconds • flush 240 seconds • hold down 180 seconds

  7. RIP Configuration • Activates the RIP routing process on the router Router(config)#router rip

  8. RIP Configuration Identifies interfaces to activate and networks to advertise Router(config-router)#network network-number

  9. RIP Configuration • Passive-interface command prevents sending but not receiving Router(config-router)#passive-interface s0

  13. RIP v2 • Enhancements • Sends to 224.0.0.9 • Sends mask – supports VLSM • Supports authentication

  14. RIP v2 Configuration • Enables version 2 Router(config-router)# Version 2

  15. RIP v2 Configuration • Disables auto-summarization at classful boundaries Router(config-router)#no auto-summary

  16. Show Commands • Show ip protocols • Sh ip interface • Sh ip rip database • debug ip rip
