Unable to ping interface on the router

[sridhar ch]

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.

do you have any ACL blocking the icmp?

Is there any NAT configuration with this subnet range?

If possilbe get us the running config.
