Andy,
Good question, for me at least. I think the route tables will show R1 as
the next hop if that is where the destination is from R2, but type 3,4,5
LSAs must get flooded to the backbone (area 0) by virtue of the Vlink and
then out to area 1 via the ABR.
Take Care

Hi Andy,
Without the Vlink, R2 is not part os the OSPF domain at all. With Vlink R2
becomes part of the OSPf domain and should calculate spf topology to go
through R1 for all networks (R1 is tunnel). Therefore I believe next hop
will always be R1 for all R1 networks and in fact all OSPF networks. This is
only logical thinking though, I have not confirmed confirmed in lab. HTH.

Guys,
I wonder if their is anybody who remembers the discussion on Virtual
Links in OSPF. It was posted some time ago but I can't seem to find it.
The scenario was something like this:
________ _______ _______
|Area 0| |Area1| |Area2|
| R0 |--| R1 |--| R2 |
|______| |_____| |_____|
There is a virtual link from area 2 to Area 0 via Area1. Traffic needs to
get to R1 in Area 1 from R2 in Area 2. Assume that the virtual link has to
use R1 (To create the V.Link). Does the traffic flow passed R1 (in Area 1)
to Area 0 and then back to area 1, or does the actuall flow just to R1 from
R2.
I cant remember the conclusion, and I cant seem to find it on the archives.
Quite interesting issues.
Regards,
Andy
