I have a Dailer interface with two BRIs that belong to it. I use the BRIs to backup a frame relay circuit. I have to support up to 256k of bandwidth so i needed four bearer channels. I recently had a problem with the ISDN line that is BRI1/1. I noticed that while this line is in a non-functioning state (it is unable to dial long distance, layer 1 and 2 are still up though) the DDR will not dial and come up when my frame relay drops. It's as if the router will only try using BRI1/1 and as long as calls fail it will not cycle to BRI1/0. If i shut the BRI1/1 interface everything works fine and it will dial using BRI1/0. I was under the impression that when you have more than one interface belonging to a Dialer it would cycle through each interface. When the other interface is functional everything seems to work fine (or as i said, currently with BRI1/1 not being able to dial long distance it will bring up DDR on BRI1/0 if i down the BRI1/1 interface).
Here is my configuration:
interface BRI1/0
no ip address
encapsulation ppp
no ip route-cache
no ip mroute-cache
load-interval 30
no keepalive
dialer pool-member 1
