We have uab+ running on a SUN3/80 (SUNOS4.0.3 -- dont ask), two Shiva boxes, kip
on a SUN3 machine, and 3 ethertalked Macs.  All of these are on the same subnet.

                uab+ (zone=Sol)               kip (zone=Apollo)

atalkad configures both Shiva boxes. Anyway, after a while the net starts
getting really bogged down, and the problem is that when uab+ comes up it gets
told (by one or both of the shivas) that there is a net 0.0.  It seems like the
distance (number of hops?) is 132!!  I`m not sure if this problem happened
recently or if it has always been around as our network has been in a state of
flux for some time now.  New macs have been added recently.  Could this be a
Phase II incompatibiliy?  How are Phonenetted macs configured for Phase I or
Phase II atp?

Here is the uab output...

There is more when the other bridge info comes in, but after that is just keeps
trying to find a good route for net0.0 again and again, but there are too many
hops.  


Any ideas.  Please mail direct if this is a frequently asked question that
everyone except me knows the answer too.
