Configuration verification
1) Display data forwarding paths when the main link of the OA server between Switch A and Switch C
works normally.

Precautions
1) When you configure the apply cost command in a route policy:
z
The new cost should be greater than the original one to prevent RIP from generating routing loop in
the case that a loop exists in the topology.
z
The cost will become 16 if you try to set it to a value greater than 16.
z
The cost will become the original one if you try to set it to 0.
z
The cost will still be 16 if you try to set it to 16.
