We are having a considerable problem here with zone information dropping out
of the chooser at random intervals.

The scenario:

a) Two Webster multiport gateways, one running transition ethertalk routing
   (hence our phase 2 network has a single net number range)
b) Two Kinetics fastpaths - phase 2 only
c) DEC VAX running LANworks (phase 2) and acting as the seeder
d) a cisco with phase 2 routing turned on. (an IGS running 8.2 rel 3)

I know I can't exhaustively provide the whole scoop here as to our network
setup, but ever since phase 2 routing was turned on in the cisco, problems
have turned up with *all* zones disappearing from the chooser on ethernet
connected macs (sometimes only a few disappear - this occurs if the Mac is
on phase 1 or 2).

Has this problem turned up elsewhere, and if so where should I start 
looking to track this sucker down ?? I'm _very_ perplexed by what is 
going on. I don't really want to hang a sniffer on my net and look at all 
the packets :-) .....
