I'm switching between dialup so I can get to the racks, and my
cable modem to send mail. I sent Kevin a response but I don't know if
it got out, so I'll try again.
I disabled RTMP split horizon on the hub sub, and now the pings
work. Why would a routing issue involving split horizon prevent nodes
on the same cable range from communicating? Both spokes see the hub as
a neighbor, and if I do a show appletalk route 500, which is the cable
range and zone that all three share, its there. The frame (layer 2 to
layer 3)mappings are there.
In an IP environment, all that would be needed is the layer 3 to
layer 2 mappings if they were on the same network. Even if you had rip
on there, it wouldn't make a difference cause it is directly
connected.
Obviously, I can't apply that logic to AT. What am I missing? Its
working but I don't understand why.

Hi all. Still bangin away here, and have run up against another
wall. I've got a hub and two spoke routers running frame. I have IP
enabled on all. The hub has a map to each spoke, and the spokes have a
map to the hub and the other spoke. Everyone can ping everyone and
life is good. Interface is multipoint and they are all on the same
net. It is also a sub-interface.
Now enter appletalk. I bascially configured appletalk the same
way. The hub has a mapping to both spokes, and the spokes have a
mapping to the hub and the other spoke. They are all on the same
cable-range and zone, differnt nodes. The hub sees both spokes, and
can AT ping both spokes. The hub can also see other zones off
ethernets on the spokes. The spokes can AT ping the hub, but not the
other spoke. I've checked the mapping and they are there. I've
debugged appletalk packet, but am having trouble deciphering it.
I was expecting AT to work basically like IP over the frame, but
not ever doing AT, is their a gotcha I don't know about?
I'm continuing to search, but have been stuck on this for about 2
hours now. Have all the books out but haven't seen anything yet.
Thanks!
