Hi Geoff,
Just a small possibility.... Double check on what circuit is termining on the physical interfaces. What I mean to say is, if the two ends are not connected to the same circuit physically too, it might show you up/up (due to some other ends connectivity) but it won't be the result what you are looking for. Show cdp neighbor command can help you in this i.e. if some other Cisco router is getting connected ypu can see that in place of desired router. It had happened with me, so maybe it's the cause.....

Both sides' subinterfaces are "up/up", but I am not able to ping either IP address, even when I am on the host router for each address! Both sides have other working subinterfaces which I have tested similarly, and these use the same physical circuit, so I know the circuit is good. OH... and this connection WAS working at some point, but I can't tell when it stopped working, due to the fact that neither router recognizes that there is a problem. I tried bouncing both subinterfaces and reloading the 2500, but the problem remains. Any advice about what I may be overlooking would be a Godsend. Thanks!
