Need Help troubleshooting. I would like someone to look a my config for frame relay backup and tell me if I miss something. Yesterday I went to my remote site and shutdown the interface for frame relay to see if the backup scheme would work. I'm using a dialer watch scheme. As soon as it loss the connection it works a plan it dial up the central site. However from a desktop I was not able to establish any connecton to a server. I was able to ping the server from the router but no connection from the desk top. I believe its a routing issue but
either I too close or overlooking the obvious. Also when shut down the remote site and it establish a isdn connection all the other remote sites connected as well. If you can help thanks in advance. Here is example of the config at the remote site.interface BRI0
I do have that route added I just have the metric of 150 instead of 250. No auto-summary is turn on also.
I have also turn on passive-interface on the remote router so no router updates will be going across the link. What I think I overlook was there were no route on the central router under router eigrp 2 or a even a static route. I won't be able to test a can until next week. Thanks for responding.
The only way I got it to work was to add static routes to the central router. But the problem I having now is the link is flapping. Channel one will come up then channel 2. Then channel 1 will drop out
Any Ideas you can offer. Thanks if you can help me.
I've seen this isdn channel flapping before....it's related to the chap authentication. It looks as if you don't have a username/password pair set up on the remote router, so when the call is established, the remote site doesn't know who is calling in....when it has data for the central site, it makes another call using the second B channel back to the central site. The channels are dropping because they are timing out(no more data to send)and it looks like they are flapping....
