We've got a 200-net AppleTalk internet spanning 3 countries and 2
continents, comprised exclusively of cisco routers and Kinetics
FastPaths, all speaking vanilla, IP and EtherTalk Phase 1 protocols.
We're very happy with the cisco gateways.  No box is perfect, but the
cisco has very good debugging & test features and their support has
been excellent.

As you no doubt discovered, this has nothing to do with the cisco and
every thing to do with the protocol which the FastPath manager speaks.
(I'll give you a hint:  it's not IP and it's not AppleTalk.  Here's my
vote that Shiva does the Right thing and supports FastPath management via
IP.)

Amen.  You cannot build a large network with bridges. [but ahem,
I really would like ATP2 support on cisco's soon...   :^)  ]
