Questions and Answers

What is the Routing Information Protocol (RIP)?

RIP is one of the oldest distance-vector routing protocols which employs the hop count as a routing metric.

How does RIP prevent routing loops?

RIP prevents routing loops by implementing a limit on the number of hops allowed in a path from source to destination.

What is the largest number of hops allowed for RIP?

The largest number of hops allowed for RIP is 15.

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- Poison Reverse, which sets the hop count to 16 for routes that are no longer valid.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.
