Dear all,
Hi.I have configured a cisco 3640 router to connect to seven 1721 remote routers at remote sites through frame relay and everything is working just fine. I configured the subinterfaces and everything is ok. My problem started when I had to configure a PRI E1 ISDN line to backup the frame relay in case of failure.. I know I should configure the remote router to call the main one but I don't know how to configure the main 3640 router. How do I setup the E1 controller and how should I divide it to subinterfaces? Is it something similar to frame relay DLCIs??! Here is my main router config
version 12.3

Hello,
basically, you will need to define dialer interfaces and use those interfaces in the backup interface statement on your frame-relay subinterfaces. I have made a few additions to your configuration (additions are marked with -->) and added Dialer17, try if this works and then add the other dialer interfaces for the other remote sites accordingly:
Let me know if this works, if not, post the configuration again with the additions you have made so far, it might get easier then to see if anything is missing...

service timestamps log datetime msec
no service password-encryption

--> username Remote 17 password xxxx (the password has to be the same on your remote site, with the name of your 3640 router as the username)
