I did have source bridge spanning on the interfaces, it still didn't work.
The only time it worked was if I used the dlsw bridge-group command and put
the token ring interface into that bridge group. I noticed you said that
you do require the source bridge statements, but that doesn't seem to be the
case, after I found that I got it working with the bridge group commands I
removed all the srb commands and it still worked with no srb commands on the
router. Why do you say you have to have them, are there certain situations
where they are required, and some where they are not? By the way, my ASCII
drawing didn't come out very well so I figured I would give it another shot
below, any responses are appreciated:
workstation--e0--r1--/\/\/\--r3--to0--to0--r6(bridge)--workstation

Guy,
You also need the source-bridge spanning command on the token
ring interface. This command enables spanning tree explorers. I assume
you're testing using a windows workstation and enabling netbeui on you
NIC. If so, you MUST enable spanning tree explorers to see the shares
across the network if you use SRB.
On your other comment, YES! You need SRB commands with token ring
interfaces in DLSW. The router uses SRB to get from the physical ring
through the "bridge" to the virtual-ring you created with the command:
Source-bridge 1 1 12
DLSW picks it up from the virtual ring.
And lastly, this WILL work with the transparent bridging commands as you
suspect. Try it out man...post your results to the group.
Aloha, Frank

In documents that I have seen, it shows that on a token ring router
running
dlsw, all that is required is a source-bridge command i.e.
"source-bridge
ring-group 12", and on the interface "source-bridge 1 1 12" linking the
interface to the virtual ring. I set up dlsw between a token ring
router
and an ethernet router, I don't have a token ring workstation so I set
up
one router with ethernet and token ring as a transparent bridge as seen
below. But it didn't work like I thought. I could not get it to work
with
the source bridge commands, but when I made the token ring interface
part of
a bridge group and put in the dlsw bridge-group command, it worked with
no
problem, I could find the other workstation and transfer files. I have
also
seen configs where an ethernet router has a source bridge command when
peering with a dlsw token ring router. When do we use the source bridge
commands in dlsw, are they really necessary, or can it be done just
using
bridge groups? I included an ASCII drawing of what I had set up below,
maybe the source bridge commands didn't work because I had this setup
with
the transparent bridge?
