I've been thinking about this one. I'm not too sure, and will have to
try it out in the lab, but this could possibly be done by having two
virtual links. My thinking is that as a virtual link over one area
causes area 0 to be extended to the end of that virtual link, couldn't a
second virtual link be created to attach to the new 'extended' area 0?
e.g in the diagram, create a virtual link between area 2 and area 0 over
area 1, extending area 0 to R2. Then create a second virtual link from
area 3 over area 2 to R2.
As I stated, this is just theory (my kit is tied up running a BGP lab),
but it could be worth a go - you never know, it may work!

Vaughan

Hi
I remember reading the OSPF RFC a while ago and I think it is not
possible.
Thanks
