Hi,
We have 2 LNS that are part of a SGBP group. Users can connect with
multiple same type interfaces no problem. For example the customer may
have 2 ADSL wics in an 1841. So looks to be functioning correctly.
However we have another style of customer who has an ISDN bri and an
ADSL wic in an 1841. The ISDN is backing up the ADSL with a dialer
watch command. When the watched route disappears the ISDN comes up
fine. So the first part of the job seems to be working okay. However
when the ADSL interface comes back and tries to reconnect this fails.
The usernames are different and different IP addresses are assigned.
From the debug it would appear that the remote router is trying to
join the interfaces into the one multilink bundle because the mppp
bundle-name discriminator is the same. I have tried influencing the
discriminator at both ends but it always uses the SGBP group name on
the customers router. We don't want both interfaces in the same bundle
for various reasons but we do require mppp on both links.

Anyone seen this before? Is there a way around it?
