Study Notes

Routing Information Protocol (RIP)

  • RIP is a distance-vector routing protocol that uses hop count as its routing metric.

Routing Loop Prevention

  • RIP prevents routing loops by implementing a maximum hop count of 15, which limits the number of times a packet can be routed through the network.

Hop Count Limit

  • The largest number of hops allowed for RIP is 15.

Incorrect Routing Information Prevention

  • RIP implements two mechanisms to prevent incorrect routing information from being propagated:
    • Split Horizon, which prevents a router from advertising a route back to the router it learned from.
    • Poison Reverse, which sets the hop count to 16 for routes that are no longer valid.

Limitations

  • RIP is not the preferred choice of routing protocol in most networking environments because it has a limited hop count, is slow to converge, and is vulnerable to routing loops.

Routing Table Updates

  • RIPv1 routers broadcast updates with their routing table every 30 seconds.

Routing Metric

  • RIP employs hop count as its routing metric, which means the number of routers a packet must pass through to reach its destination.
