Curiosity. With the multipoint problem, I am wondering if using a tunnel
would solve the multipoint issue? Tunneling seems to be one answer to many
multipoint issues.
If I can find your configs here somewhere I will try it, or if you could
post them again I would like to see if tunnel would fix it. I would think
off the top of my head it would but.......

Subject: RE: dlsw pass-thru THE ANSWER AT LAST
Thanks to Kivas he pointed me in the correct direction to obtain the answer
which I so so looked for, for the last 24 hours.
All in All there were 2 things on my lab which was stopping the pass-thru
from working. Firstly I had the local peers as IP addresses i.e.
dlsw local-peer peer-id 123.123.12.12 this appears to be pointless as you
are doing a direct encapsulation and should just be dlsw local-peer
Secondly another thanks to Chris Stephenson on this one but the fact that I
was using a multipoint interface also stopped the peering. I tried a point
to point interface and to my surprise and horror it still didn't work. So I
then tried to put it on the physical interface and BANG it all
exploded into life.
So in a nutshell... If you area doing direct encaps with pass-thru it has
got to be on the major interface and you just have to specify dlsw
local-peer.
For those who are remotely interested in this the debug dlsw command was
giving me the answer of the major interface as despite the dlci being on
either a multipoint or pointtopoint interface the debus kept reporting an
encaps fail on the major interface. Try it and see its good fun NOT.
Thanks to all who contributed to this thread and I hope from it others don't
have to suffer as much as we all have over the past 24 hours.
Cheers.

Hi Robert, mine worked, here are the configs trimmed down to the important
bits. Sounds like you might have an IOS issue.

Fellow members,
I am now going to have a break from the exhaustive studying I have done in
the last 3 weeks for 2 hours. If anyone comes up with a suggestion I will
try it and get back with the answer in around 2.5 hours. Around 22:30
scottish time.

Have you tried to specify the frame size (lf) ? I had to do that last time
I configured it...
