I ran into something very similar a while back. For some reason, maybe
others can tell us why, the provider did not want LMI enabled. I believe
we had to enable it to bring the PVC up but after that they toggled LMI off
and told us to add a "no keepalive" statement and it worked fine. If we
did a "sh fram pvc", the PVC in question was listed as "static" instead of
the usual "active" (or "inactive" ;-)). Sounds like LMI isn't really enabled.
