I am trying to configure dial backup between two Cisco routers. When the remote router dials into the central router, you can hear the central router answer, but it does not begin the handshake until two or three seconds pass. During this time, the remote router drops the connection.
How do you fix this?
Any help would be very much appreciated!!!

Hi,
Are you using PPP ?
If yes, can you post the debug ppp negotiation and debug ppp authetication and debug dialer results.

Yes I am using PPP. I will post the output from these debugs later today..
Thank you,

Here are the debug outputs you requested. When the remote router dials out and connects to the headend router, you can hear the headend router answer, but it seems to take too long to begin negotiating and the remote router just disconnects.
You can hear the same thing if you call the dial-up number using a phone. The router answers but then there is a pause of a couple of seconds before you hear any modem tones…

Hi,
Is it possible to capture the configuration output from both ends?
Regards.

Hi,
Thanks for the configs, is ti possible to enable below debugs:
- debug modem
- debug confmodem
- debug chat
What model/brand is the modem you have connected to Aux port of National router?
Have you tried removing chat script backup from under line aux 0?
Regards.
12-07-2011 08:08 PM
Juan
Thank you for the reply. I am using a US Robotics modem(not sure of the model now)....
I will do he debugs Friday morning and post them. I will also remove the chat script then also.
You are wanting to see the above debugs from the National router, correct?
Thank you again!!!
12-08-2011 04:38 AM
Hi,
Yes please capture the outputs from the National router. Depending on the model we can try different scripts. Let me know how it goes.
Regards.
12-12-2011 07:36 AM
Juan,
Ok, getting closer... I removed the chat script backup from line Aux 0 and now I am able to connect to the head-end router but now I do not seem to be authenticating. I have made sure the usernames are created on both routers and I reset the passwords, so I know they are correct on both ends. Can you take a look at the debugs and tell how to resolve this???

Hi,
There is a problem with authentication for sure, National device sends out a TERMREQ once it receives credentials from remote RameyGO router. Have you verified credentials, passwords at both ends must be the same.
You can also try to disable AAA from National router (it is configured to use local authentication but it would be worth to try without it).
If you would like to use different user/pass combination then you can make use of the "ppp chap hostname
