I encountered a problem where I had a NSSA area that was not adjacent to Area 0
. So I created a virtual link to attain my adjancency. The virtual link came up
.
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 NSSA
were a VLSM with a /25 mask. So I changed this to a /24.
As soon as I did this all the routes were pulled into the NSSA router. I went b
ack and made the address a /25 again and once again the routes were gone. Then
I tried summarizing using area range and, summary address. But that did not wor
k.
My question is. Are there any specific rules to the use of Virtual Links or NSS
A that anyone knows of that pertain to the addressing/mask? I have searched the
doc and I have found nothing.
Area 0
R1 Area 1

| Area 1
R2 Area 2 NSSA

| /25 mask on link between 2 and 3

R3 Area 2 NSSA
thanks,
Jerry
