I'm not at all conversant with the Appletalk protocols, hence my
naivette may be showing...

We need to provide a couple of separate groups of Mac's with the
capability of talking to each other via Appletalk (for file exchange,
access to a mail server, etc).  The existing transport medium is
a couple of Ethernets connected by cisco boxen.  The intention is
to use Apple's own Appletalk Internet Router (did I get that right?) software
on a dedicated Mac-per-lab to gate between Localtalk in the labs and
Ethertalk between labs.

Now, it is my understanding that cisco's (we're running 8.0(13) software)
are compatible with the Ethertalk V1.0 software but not Ethertalk V2.0.

o Is is sufficient to ensure that my gateway Mac's are running Ethertalk V1.0
  and everything will play together without a hitch?  [He asks, hopefully :-)]

o Has anyone 'out there' used the Apple Internet Router software in
  conjunction with cisco's routing Ethertalk?  Are there any caveats
  that we should be aware of?

o Is Ethertalk addressing so radically different from Localtalk?  Part of
  my confusion arises from my impression that Appletalk V1 uses 8-bit
  addressing and Appletalk V2 uses 24-bit addressing...  but cisco's
  documentation says that they deal with 24-bit Appletalk addresses
  and yet only support Appletalk V1.  Huh?

Thanks in advance to any and all that respond,
Eriks
