Hello Jerry,

Try to search out bug toolkit on CCO. I saw somthing about it
recently...

BTW, I was wondering if you send your configs.

JH> I encountered a problem where I had a NSSA area that was not adjacent to Ar
ea 0. So I created a virtual link to attain my adjancency. The virtual link cam
e up.

JH> However my routes to the NSSA area never got forwarded, I tried everything
with no luck. Finally I noticed that the link between the two routers in the N
SSA were a VLSM with a /25 mask. So I
JH> changed this to a /24.

JH> As soon as I did this all the routes were pulled into the NSSA router. I we
nt back and made the address a /25 again and once again the routes were gone. T
hen I tried summarizing using area range
JH> and, summary address. But that did not work.

JH> My question is. Are there any specific rules to the use of Virtual Links or
 NSSA that anyone knows of that pertain to the addressing/mask? I have searched
 the doc and I have found nothing.

JH> Area 0
JH> R1 Area 1

JH> | Area 1
JH> R2 Area 2 NSSA

JH> R3 Area 2 NSSA
