If there are any "ospf/E2" (type 7) routes being generated by the
PMs that need to get out, then the area needs to be NSSA or transit
(external). These are typically any IP addresses assigned to a user
that are not part of the 'assigned pool' - ie. a static IP address
is some other range - or some static or RIP route being redistributed.
Even if the area is a transit area, these routes will remain as type 7s.

>>Also...why no route filtering/mapping on the PM2?
The filtering code is part of the BGP module and only the IRX and
PM3s have it. I've personally asked for this to be changed, but I will
do so again!
All the best,
