Meanwhile, Router C would send update to Router B about the lost route. In order to prevent this, the protocols such as RIP have maximum hop count. The maximum hop count for RIP is 15. A route with higher maximum hop count will be unreachable and cannot be used. Once Router B gets this update from Router C, it will add another hop count and will make it 4. This cycle will continue. Without the established maximum hop count, the accumulation of added hop counts will cause the routes to be unreachable, and will be eliminated from the routing table that will cause the loop to be resolved.
