Routing Information Protocol (RIP) is one of the oldest distance-vector routing protocols which employ the hop count as a routing metric. RIP prevents routing loops by implementing a limit on the number of hops allowed in a path from the source to a destination. The maximum number of hops allowed for RIP is 15, which limits the size of networks that RIP can support.

Here are the steps of how RIP works:

1. Initialization: When a router is powered on, it initializes the RIP by sending a request message to all its RIP enabled interfaces. The neighboring routers respond with all their routing tables.

2. Update: After initialization, the router updates its routing table every 30 seconds. The updated routing table is then sent to all neighboring routers.

3. Route Change: If there is a change in the network topology, the router sends an update immediately to all neighboring routers. The routers then update their routing tables and propagate the change to their neighbors.

4. Route Expiration: If a router does not receive an update about a route for 180 seconds, it marks the route as unreachable. If it still does not receive an update for the next 120 seconds, it removes the route from its routing table.

5. Route Selection: RIP uses the hop count to select the best path. The path with the least number of hops is considered the best path. If there are multiple paths with the same number of hops, RIP uses load balancing to distribute the data.

6. RIP Timers: RIP uses different timers to regulate its functions. These include the Route Update Timer (30 seconds), Route Timeout Timer (180 seconds), and Route Flush Timer (240 seconds).
