1.1.5.0/24, cost 2, nexthop 1.1.2.2

The output shows that two RIP routes can reach network 1.1.5.0/24. Their next hops are Switch B (1.1.1.2)
and Switch C (1.1.2.2) respectively, with the same cost of 2. Switch C is the next hop router to reach

network 1.1.4.0/24, with a cost of 1.

(1.1.1.2) and a cost of 2.

Troubleshooting RIP

No RIP updates received

Symptom:
