Unable to ping interface on the router

Hi,

I have a strange problem here. I have a 2800 router with 3 active interfaces. I am unable to ping the IP assigned to one of the interface though it is showing as up. Able to ping the other 2 interfaces.The other end is connected to Checkpoint FW. what could be the issue?

Thanks,

Sridhar

Hmm...looks strange can you provide us the config and outputs you are trying to ping?

R u trying to ping your own interface ip address? If the interface is upthen you need to ping the ip address configured.
