Mani,
I'm still a bit confused as to the requirement.
The purpose of DLSw is to take non-routable traffic (SNA/NetBIOS) and
allow it to transit an IP network. (At least, if you're using TCP
encapsulation.)
If I understand you correctly, you are taking traffic from Vlan 5, to
which R2 is connected, encapsulating it via DLSw at R2, and then sending
it to R1, which is also connected to Vlan 5. What confuses me is that
there isn't much point to using DLSw when R1 and R2 are connected to the
same Vlan. Why pick traffic up from vlan 5 on R2, encapsulate it in IP,
and then send it to R1, when R1 is connected to the same network? I'm
thinking either (a) you misread the requirement, (b) I misunderstood
your description of the requirement, or (c) I'm not clear on how DLSw
works. (A definite possibility, despite the CCIE, believe me...)
Thanks, and Happy New Year,
Jeff McLaughlin

Hi Jeff,
Thanks for getting back to my email. Yes bridge group command is on
both vlan 5 and vlan 10. What I am trying to achieve is to make vlan 5
of hub talk to R2 e0 and vlan 10 of Hub talk to R3 e 0. The objective
is to make sure R3 e0 doesn't talk to vlan 5 of hub and R2 e 0 doesn't
talk to vlan 10 of hub.
thanks

Mani,
I believe bridge-group numbers are locally significant, so they
do not
have to match on different routers. However...
The e0 interfaces on R2 and R3 which have the bridge group on
them...
Are these on vlan 5 and vlan 10? Or are they on another vlan? If
they
are on vlans 5 and 10, I'm a bit confused about what you are
trying to
accomplish here. If I'm not mistaken, you're basically bridging
those
vlans into DLSw, and then shipping it off to R1, which happens
to also
be connected to the same vlan. I think you would normally bridge
a
network that R1 _isn't_ connected to.

Hi Guys,
Look at the following config of dlsw where the hub, R1 has 2
vlans(e0-vlan5 and e1-vlan-10). Now requrement says spoke R2
must make
dlsw session with vlan 5 and spoke R3 must make dlsw session
with vlan
10.
R1 configs:
dlsw local-peer peer-id 10.1.1.1
dlsw bgroup-list 1 bgroups 1
dlsw bgroup-list 2 bgroups 2
dlsw remote-peer 1 tcp 10.2.2.2<--Look for 1 and 2 numbers
dlsw remote-peer 2 tcp 10.3.3.3
dlsw bridge-group 1
dlsw bridge-group 2
bridge 1 protocol ieee
bridge 2 protocol ieee
e0 -if)#dlsw bridge-group 1<--vlan5
e1 -if)#dlsw bridge-group 2<--vlan10
R2 configs:(connecting to vlan 5 of R1)
dlsw local-peer peer-id 10.2.2.2
dlsw remote-peer 0 tcp 10.1.1.1
dlsw bridge-group 1
bridge 1 protocol ieee
e0 -if)#bridge-group 1
R3 configs:(connecting to vlan10 of R1)
dlsw local-peer peer-id 10.3.3.3
dlsw remote-peer 0 tcp 10.1.1.1<--Note is 0 tcp
dlsw bridge-group 1
bridge 1 protocol ieee
e0 -if)#bridge-group 1
Now my question, since R3 is connecting to vlan 10 of R1(belongs
to
bgroups 2), is my config for R3 is right or it should be dlsw
bridge-group 2/ bridge 2 protocol ieee and bridge-group 2. Any
clarification regarding this configuration is appreciated.
thanks
Mani
