Hello.

We've got a 1721 utilizing ISDN Dial Backup (BRI0). Here is the BRI0 config:

Code:
interface BRI0
 description ISDN Dial Backup
 ip address negotiated
 ip nat outside
 ip hello-interval eigrp 100 3
 ip hold-time eigrp 100 9
 encapsulation ppp
 dialer map ip XX.XX.XX.XX broadcast XXXXXXXXXXX
 dialer watch-group 1
 isdn switch-type basic-ni
 isdn spid1 XXXXXXXXXXXXXX XXXXXXXXXX
 no peer default ip address
 ppp ipcp mask request
 ppp ipcp address accept

Everything works fine. The problem is once the dial backup is forced up and then goes down once the Frame Relay comes back the configuration lines "ip hello-interval eigrp 100 3" and "ip hold-time eigrp 100 9" disappear from the config. And next time the dial backup is forced up it's got the default EIGRP timers. Why is this happening?? Thanks.
