This happens becaue the virtual link PUTS R4 in area 0. That's the whole
idea behind a virtual link. So now the routes it learns are intra-area. I
don't know why you'd ever need to summarize area 0 into R4 once the virtual
link is created. Routers in the same area must have full routing
information for that area - by design.

Subject: Virtual-link and Area range
Hello,
This question might have been asked before but I just could not find
anything about it in the archives.
Topology:
Area 2 /25 ---- R4
s1
|
|
Area 1 10.2.2.x/28
|
|
R5
s1
|
|
Area 0 10.2.1.x/30
|
|
R3
Before virtual link is enabled, I can see the /24 of Area 0 at R4 due to
area range at R5. After I enable the virtual link on R4 and R5 over area 1
the /24 is no longer at the routing table of the R4. Also, before the
virtaul link the route for 10.2.1.x was OSPF Inter-area which makes sense
but after the virtual-link was enabled the route looks like an intra-area
route, no IA. Can somebody shed some light on this? There has to be a way
to advertise a summarized network to R4 whe virtual link is enabled.
TIA
