We are having a problem (misunderstanding?) with connecting an
IBM token ring to an ethernet. Currently, we have the following
network:
--------
| | (token ring with MACs running appletalk,
Net "A" | T.R. | PC's running TCP/IP and NetBIOS)
| | This token ring is bridged to lots of other rings.
--------
|
IBM 8209 (Ethernet to TR bridge)
|
Synoptics pseudo-ethernet (not much on this ethernet)
|
Bridge IB/3 remote bridge
.

Bridge IB/3 remote bridge
|
Net "B" Synoptics pseudo-ethernet (with MACs running appletalk, PCs
running NetBIOS and TCP/IP and lots
of other stuff). This ethernet is
bridged to lots of other ethernets.
Currently, all protocols are bridged between the ethernet and the
token ring, and everthing works well. We now want to use a cisco
to route IP and Appletalk between ethernet B and token ring A.
The problem is that (apparently) a cisco cannot replace the IBM 8209's
functionality. It can route IP (and Appletalk?) between the TR and
ethernet, but it can't bridge the other protocols (e.g. NetBIOS).
Has anyone:
a) routed appletalk between a token ring and an ethernet?
b) bridged NetBIOS between a token ring and an ethernet?
c) got any idea how to route IP and Appletalk and bridge
NetBIOS between a token ring and an ethernet using a cisco?
How about using the 8209 and a cisco?
Note that the Cisco at the site where net "A" resides is an AGS+ with
one token ring card, and a 2E2T card. Eventually, we will have an
AGS+ at the net "B" site to connect to the AGS+ at the net "A" site
replacing the IB/3 bridges.
Thanks a lot.
