As previously mentioned in another post, your shared secret is not the same on both username/password combinations for both routers. As you indicated, you had a copy/paste error and I do not necessarily believe that is the root of the problem, because your debugs (which appears to be "debug ppp neg" or possibly "debug ppp auth" does not explicitly indicate a CHAP failure. It would be clearly indicated. There appears to be other issues at work.
One of the first things that caught my eye was why you set the interfaces to unnumbered, but pointed them to different IP networks, namely 192.168.3.1/32 and 192.168.2.1/32. Just out of curiosity, why not place the interfaces on the same IP subnet, such as 192.168.2.1/30 and 192.168.2.2/30 for the other side? That is still not going to cause the problem you have, because your debug seems to indicate you are not getting past layer 2. I was also curious as to why only one side of this backup link was allowed to detect and initiate failure? Specifically, you have a dialer map statement from Ney York to Albany, but you have no dialer map statement from Albany to new York? Was this intentional? I also noticed that you have indicated the intent was to use the AUX ports for a dial backup solution (I assume in the event that the frame relay circuit goes down between the two locations). What is not clear looking at the configs is how this will be accomplished without the use of the backup interface command or dialer profiles (which is probably better). Additionally, I do not see how packets sourced from the Ethernet interface on either router will have a path to the other ethernet interface on the far side router. You do not appear to have enough routes on each routers' static route statements to make it all work. Still, this is not causing the problem you have. My bet is that the problem you are having is related to this command here: ppp authentication chap callin You may want to read this link (watch wrap) to understand why that command may not be necessarily appropriate for what you are trying to do: http://www.cisco.com/warp/public/131/ppp_callin_hostname.html HTH, Paul Werner > Hi all, > > I am configuring 2 router from their aux ports (but not back to back) > with > usr modems.
