What I wanted to do was just set up dlsw between a token ring and an
ethernet router, nothing extravagant with no fancy tricks, precisely because
I had seen some documentation stating that on a token ring router, all that
was needed to link the interface to dlsw was the "source-bridge ring-group
x" command in global config mode, and the "source-bridge x x x"
"source-bridge spanning" commands on the interface. So I set it up, and it
didn't work for me. So then I figured I would try to use the "dlsw
bridge-group x" command with the "bridge-group x" command on the token ring
interface to link it to dlsw. I did this, and it started working exactly as
it should. I am just wondering why it was working this way and not the way
that the documentation says it should. I will set it up again this weekend
and send you guys some more detailed outputs and configurations, thanks.

Hi Lupi,
Your changes is to configue as TB(transparant bridgeing) instead of
SRTLB, it this what you want ?
You have not configure bridge group protocol.
Since you are using IP as transport for the DLSW, you should ensure the
IP reachability and test with other protocols for the bridgeing.

Here are the configs, first the ones that didn't work, and then the
added
commands to the token ring router that made it work as I expected,
thanks
for your time:
r3
source-bridge ring-group 12
dlsw local-peer peer-id 3.3.3.3 lf 1500 promiscuous
dlsw remote-peer 0 tcp 11.11.11.11
!
interface Loopback0
ip address 3.3.3.3 255.255.255.0
!
interface TokenRing0
ip address 200.200.200.1 255.255.255.0
ring-speed 16
source-bridge 1 1 12
source-bridge spanning
r1
dlsw local-peer peer-id 11.11.11.11 lf 1500
dlsw remote-peer 0 tcp 3.3.3.3
dlsw bridge-group 1
!
!
interface Loopback0
ip address 11.11.11.11 255.255.255.0
!
interface Ethernet0
ip address 1.1.1.1 255.255.255.0
bridge-group 1
But if I put the following commands on r3, it works no problem, even
after
the source bridge commands are removed.
r3
dlsw bridge-group 1
!
interface TokenRing0
bridge-group 1

Guy,
Please post your configs. The dlsw source-bridge command is ONLY used
for
bridging the ethernet bridging domain to DLSW. If you send your configs
I
can see what is going on.

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?
