Refer to the exhibit. R1 and R3 are connected to each other via the local serial 0/0/0 interface. Why are they not forming an adjacency?
- They are in different subnets.
- They have different routing processes.
- They have different router IDs.
- The connecting interfaces are configured as passive.
Answers Explanation & Hints:
The routers need to be in the same subnet in order to form an adjacency. The routing processes can be different on each router. The router IDs must be different for routers that participate in the same routing domain. The interfaces are not passive.
