We have 3 sites, with a 3640 at the central location, and a 2611 at each remote site.
We are running IP only across Frame-Relay.
From my station at the central site, I can ping the 3548s that are connected to the 2611s, but not the ethernet interfaces of the 2611 themselves.
Any thoughts as to why? The answer is probably obvious, but I just can't see it.
Thanks.

Greetings:
Hmmmm...it is not so obvious.
- Are you doing "IP unnumbered".
- Could you put the config of the 3640 and one of the 2611's here. W
- What is the IP address and mask on the 3548 to that site.
- Could you also provided the IP addresses/Netmask of the other routers?
- Have you tried running a "debug ip packet" on the 2611 to see what you get?
Thanks...Steve

What I can see is that you have enabled bridging on the Ethernet / WAN interfaces and in effect you are bridging IP. Any particular reason why you are bridging instead of routing IP over the WAN ??. Once you enable IP bridging on, the ip addressess on the interfaces have no effect, and are not pingable. Thats why you are able to ping the 3548 and not the 2611. Unless you any REAL NEED TO DO BRIDIGING (i dont see), you should just turn off bridging, because its messy and adding overhead.
