Hmmm.

This makes no sense.

If you had a hope of doing this, they both need to be in the same tree. You
were told something wrong, or someone misunderstood what was wanted/needed
here.

Nope, not going to work...

The two servers shouldn't communicate if they are not in the same tree!

Anyway, this config is just goofy. Here's what I would do:

1. Get a true load-balancing/failover router (see www.xincom.com as one
possibility) to make use of both lines.

2. Cluster two BMgr servers. (Both need to be in the same tree, and
preferably in different OU's).

3. Set up load-balancing of the proxies, using DNS round-robin, with cluster
failover acting to bring either proxy address over to the other in the event
one BMgr server dies, or needs maintenance.

I've done 1 & 2 above, a couple of times. Also done 1 above without a
cluster behind it. There is a appnote on #3 above, though it's rarely
needed to actually have to load balance two proxies (because one proxy can
EASILY sustain all the traffic to a T1 + DSL line - just not enough
bandwidth there to stress it). If you need some consulting help on this,
see the URL below.
