pings don't work

[firedragon]

I'm in a cisco remote access class. The lab we are doing sets up 4 ISDN BRI (seprate 2600 routers) to dial a PRI. We get connectings estaplished between all 4 BRIs at all layers, but when we try to ping the diffrent routers one of them doses not respond to the requests. I tried a "debug ip icmp" command and the out put shows the the requests are being recived, and repleys are bing sent to the right address. But the destion of the repleys never recives them. This happens regradless of whether the link is established or not. Any ideas on what could be cousing this?

Do you have access list configured?

Hi,
On the router that does not respond try tracing the route to one of the other routers and make sure that the icmp message is being sent out of the correct BRI interface. My guess is, you have some static routing set on this router and it is sending the reply to a default route.

When ping TO the router that does not work, use the extended ping options to set the source interface to the BRI port and ping the remote BRI router.

PHil. If everything is coming your way then you're in the wrong lane.

The trace command responds the same way. And we are using static routes. We are also hooked up thought a adtran 550.
We have tried all the little tips from cisco as to get the adtran working (rebooting it 3 times, tring diffrent int.s, and so on). The routes are set correctly, and changing the interfaces on the adtran gave us the same resultes.
