I've read your posts to date.  I do not clearly understand if you have
a full iBGP mesh or not.  If you do, ASBR-B does not need to learn
FW-A's routes from ASBR-A.  ASBR-B will already be learning FW-A's
routes directly.

If you want ASBR-A to re-advertise FW-A's routes to ASBR-B then you
must use route reflection or similar.  The advertise-peer-as feature
is unrelated to what's going on here.

I hope the above gives you a starting place.  I think if you re-read
the rules for when routers will re-advertise a route to an iBGP
neighbor, you will quickly feel silly and wonder why you didn't figure
this out yesterday :)
