no, it was answered already. It has to do with bridges blocking on ports

You can just put the
DLCI's on differnt layer3 networks and it will work as is below.

different layer 3 networks though.

To me this looks very similar to bridging with DSL. Since you cannot
receive the ARP the router must proxy this.

First of all, I believe you have a typo:

should have been
router igrp 1
network 192.168.1.0
network 192.168.2.0
network 193.168.3.0
I have not an answer to your question yet.

yeah but he is using irb with a bvi and igrp it is probably a split h issue

Another thing to look at is how they are testing. If
you have a full T1 then you can have them run a 'round
robin with multi pattern' stress test. This will
break any marginal component. Some telco's will tell
you that you can't test that way on a frame circuit,
but that is only if you are not

I'm sure you meant to use 0x for the all 1's

Title: RE: challenge problem
One thing you might try is using extended ping and use different data patterns. Try 0x, 0x, 0x, 0x0810, 0x4040. I've discovered problems where certain data streams would cause problems even after the LEC says they tested. If you uncover some

Ok, I'll take a stab at it.
First a question. Have there been any BERT tests end to end (NID to frame
switch interface)? If so, was an all zero's test done?
Very simply, I suspect that one of the circuit's repeaters is misconfigured
ESF, AMI. Everything works fine until the 1's density isn't
Have you checked for clocking issues between the Router and the DSU? (garbage-in
garbage-out) I have seen that issue many times. Check the DSU's config vs a
known good config.
Are the errors also being seen on the carrier's frame-switch interface? The guys
who test the circuit do not ussually
Have you tried putting a hard-loop on the output of the CSU (that is,
disconnecting the CSU from the Router and putting a looping plug into
the port that the Router had been jacked into)?
