Cisco 2610 PPP MULTILINK BACKUP OVER ISDN

[tmontestrucq]

I have been working on a bridging configuration between two 2610.
This configuration allow me to have a bundle between the two serials and to
make a ppp multilink backup over isdn (with 4 BRI channels...And more).
Everything works fine for the dialing;that is to say that when the serial
with the backup goes down 2 call are made and then 2 others.
When the serial goes up the two first call goes down and in the same time
only one of the 2 others.
In fact the dialer is down but the multilink is up and doesn't want to
go down.

Does anybody have an idea about this problem ?

In advance thanks.
Thierry Montestrucq.



Here are the configurations of the two cisco.
