Hi,
Having looked into your problem description in detail,
I found that there's no problem in your network (see below).
(Further, I checked myself in our local setup and made it sure
that newer ospfd (0.95 and 0.95-pre2) are also properly working
with virtual-link.)
Your network configuration is:
virtual link
.............................
: :
[R0] [R1] [VR1] [VR5] [VR6]
| |.2 | | | | | | | |
---------+- | | -+--------+-- | | --+-------+-- |
10.1.0.0/24 | | 200.10.1.0/24 | | 200.30.1.0/24 |
Backbone | | Area1 | | Area3 |
---+-----+--- ---+-----+--- ---+---------
200.10.6.0/24 200.10.4.0/24 200.30.2.0/24
Area1 Area1 Area3
Notice that your text shows that R0 has summary-LSAs for
200.30.1.0 and 200.30.2.0, both in Backbone and Area1.
This indicates that VR5 is properly generating the summary-LSA
in Area1 as well.
Those routes are installed in R0 (below is quoting from your e-mail):
> ******************** R0 status *********************

R0 receives the summary-LSAs both in Backbone and Area1.
