One of the issues here might be which route is better than the other for a
particular destination.
There is only one gateway of last resort in the routing table, although
there may be more than one candidate default.
If this router is on a stub network, then it might be better to do:
ip route 0.

Hello John,
Here is my opinion. Temporarily, take the software or the workstation to the
same subnet of the Server and see if it runs OK. While it is there, you can
capture a few packets to see the conversations and the ports that are being
utilized. This gives you a pretty good idea of the goal.
It would be a pleasant surprise to me if the normal switched SPAN port
captured all your LANE traffic.
It is not supported because of the way the LECs talk to the LES and other
LECs. BUS traffic you should see very easily in an ELAN. ELANs may appear to
be similiar to Broadcast VLANS but they use

I believe that when the multicast packet arrives at an interface the TTL in

This applies even if a threshold has been set.

the TTL in the multicast packet, then th

Interesting situation. It might be that the "virtual link" is like a tunnel
and gets a different "cost" although it is a T1 line. Have you already tried
cost adjustments ? to bring the other T1's to the same level as the virtual
T1. As long as they are equal in cost there should be load balancing.
Just a suggestion. Have you tried "tagging" the routes coming into the ASBR
and then denying them on the ABR with a route map ?

It appears that there might be some small misunderstanding about DR and BDR

On a Multi-access net the DR is the "pseudonode" which represents the net.
It is similar to NLSP in this regard.

There seems to be one major advantage of using loopback addresses for

I believe that listening for RIP v2 must be done on an interface by
