Hi again,
A few last points before I sign off for the night:
1) You do indeed have to ask your users to pay attention to the error
message and do as it says (open and close the Control Panel). The person
who told me it was just an FYI message was forgetting the reality of
working with AppleTalk. (It was my husband, who was actually one of the
creators of AppleTalk. He tends to forget bad things about it. Just kidding.)
2) The Apple white paper is indeed very vague about a real solution to the
problem. &;-) But the solution is that you have to tweak the spanning tree
parameters so that the switch ports don't take so long to start forwarding
packets. Bottom line: the router's (RSM's) packets aren't getting through
in time to the end nodes so they think they are on an isolated network.
Then when they finally hear from the router, they put up that annoying
message. Another solution would be to upgrade to Mac OS X, it sounds like?!
;-]
3) Having multiple seed routers is not a problem. (Even if you had multiple
seed routers, I mean, it wouldn't be a problem. Multiple seed routers is a
good thing.)
Good luck! By the way, thank-you for buying my book. I hope you like it.
Talk to you later,
Priscilla
