Gurus- I have a situation where I am using IRB to bridge a network over a T1. I have been trying to get this backed up by using an ISDN BRI dialback with dialer profiles. I have been mostly unsuccessful except for roughly 3 minutes where it worked and then ceased working and has not worked since. The ISDN dials and connects but no traffic seems to cross the link even though lights on the front panel are flashing as though the traffic was going across normally. I was just informed by TAC that ISDN will not work with IRB and that I need to switch to CRB. This would also entail that I add an extra interface to each router in order to communicate with them via IP since CRB would eliminate the BVI's that I have been using for this purpose. My question for the group is:
* Is this true? I really have no faith in what the TAC guy told me because he really seemed to have difficulty communicating with me. * What do people use to backup IRB configurations? Has anyone else out there stumbled across this problem? *Can I use CRB on sub-if's or tunnel interfaces? Basically I am going for some sort of fancy solution that will get this working the way that I expected it would when I planned this whole setup. *Is there anything preventing me from throwing out these expensive Cisco routers and using Adtran TSU 600's which do this sort of thing in their sleep? On a related note, I am really not thrilled about the new TAC format whereby you create your own ticket on the web and then an engineer sends a link to a TAC HOW-TO article and tries to close your case. It really leaves you with the feeling that you shouldn't be paying the premium for Cisco anymore.
