Sam,
An area connected to area 0 through a virtual link is just like any other
area. It can be a normal area, a stub area, nssa, etc. Also, virtual links
can be used to join discontiguous section of area 0. Only the transit area
has the limitation of not being a stub area.

I do not have Doyle book handy right now. But I think area 0 and any other
area connected to area 0 through virtual link can not be a stub or nssa
area. Let me review this tonight and I will let you know.

Sam....
Are you sure thats the way it is?.....I thought only the transit area for
the virtual link, in this case area 51 couldnt have the stub flag set in
case....
Regards,
Vijay.

Please respond to

Hello Sara,
Once a virtual link configured in Area51 between R2 and R5, area 12 will
become part of the backbone area 0 (all backbone routes will appear as o in
the routing table, not IA) As a result of that area 12 can not be a stub or
nssa area. Please refer to Doyle 1. It has an example and good explanation.
Sam

Dear all, I am doing the cyscoexpert sample lab.
R1--area12--R2---Area51---R5---Area0 area 12 cant receive lsa type 5 routes,
so it need to be either a nssa or stub, however, there is virtual link
between r2 and r5, can r2 be configured with stub or nssa at the same time
with virtual link to r5? i thought i read it somewhere stub cant be virtual
link? Pls help.
