RFC1587 page 3 pretty much sums up the answer to your question .... quote-unquo
te.
o Type-7 LSAs may be originated by and advertised
throughout an NSSA; as with stub areas, NSSA's do not
receive or originate type-5 LSAs.
Reading this statement, I interpret it as NSSA's are like stub areas and do not
permit type-5 LSA's. Your connected loopbacks at R1 are considered type 5 LSA'
s and therefore would not enter the NSSA. You shouldn't really need the connect
ed routes entering the NSSA, a default route injected into the NSSA should do t
he trick.
Your thoughts ..... MW :)

Group,
How would you get routes E1 or E2 through NSSA as below:
area1 area0 nssa IGRP
R1----------R2----------R3----------R4----------R5
Loopback interfaces on R1 get "redistributed connected" and appear on R3 as E2
routes, but do not appear on R4.
They need to be propagated across nssa out to IGRP. Is this a mission impossibl
e?
Thanks, Voytek
