input rate

Unanswered Question

I have two WAN routers destined for the same destination. The preferred route is the second router because it has higher bandwidth. By the way, the two connections are not used simultaneously, the first router will only be used if the preferred connection (2nd router) goes down.

The connection is:

R1 <----> Headquarters

R2 <----> Headquarters (preferred route)

My question is, my R1's serial interface is receiving packets from its peer on the remote side as shown 'input rate' when issuing the 'sh int se0/0' command.

What are the possible reasons for this one ?

Those can be control-plane packets that you might be recieving, if any routing protocols are enabled on the link. Also packets like CDP etc could be increasing the input rate.

Is it significantly high? Only then you would have to worry.
