Hello Lupi,
I read your base note, you are using two WS with ethernet to test across the DL
SW, right ?
WS1-e-(R1,IP)--DLSW--(R3,IP)-to-ring-to-(R6,bridge)-e-WS2
What kind of bridgeing configuration at R6, TB, or SRTLB ?
- If R6 is configure as TB, source route is not necessary at all in this config
uration.
If you want to test the token ring to ethernet, it will be better to test using
dspu using two router ( in your case R6 and another router to r1)
Below is the example post by this group member, I have not test it before..
/////////////////////
On client (R7), do:
dspu host R6T xid-snd 01712358 rmac 4000.3745.6666 rsap 4 lsap 4
dspu host R6DLSW xid-snd 01712360 rmac 4000.3745.6666 rsap 12 lsap 12
dspu host R6VTAM xid-snd 01712359 rmac 4000.3745.6666 rsap 8 lsap 8
interface Ethernet0/0
mac-address 4000.1010.7777
dspu enable-host lsap 4
dspu enable-host lsap 8
dspu enable-host lsap 12
dspu start R6T
dspu start R6DLSW
dspu start R6VTAM
On server (R6), do:
dspu pu R7_HOST rmac 4000.1010.7777 rsap 4 lsap 4
dspu pu R7_MAINFRA rmac 4000.1010.7777 rsap 8 lsap 8
dspu pu R7_BIGIRON rmac 4000.1010.7777 rsap 12 lsap 12
interface GigabitEthernet1/0/0
mac-address 4000.3745.6666
dspu enable-pu lsap 4
dspu enable-pu lsap 8
dspu enable-pu lsap 12

Guy,
Using your original configs please send through a show dlsw peer, show dlsw
circuit, show source, show dlsw reach. Have you also taken into account that
you will either need to manually bitswap your layer 3 addresses or use the
bridge command to do this? Also, maybe a silly question, but you do have
routing between these devices? Can you ping from 3.3.3.3 to 11.11.11.11?
Also, are your peers connected? If you send the output of these commands
from both routers I can take a look. Also could you paste the full configs
from both these routers as what you have configured here is correct and thus
there must be some further issue.
Cheers.

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?
