Hi Wei,
Can you post a 'show ip ospf data nssa' from r7/r8. It may help explain
what is going on
Regards,
Lachlan

Subject: NSSA and Virtual Link Again
Hi,
I am running into problem that Type 7 LSA does not
converted to Type 5 LSA, any idea how to fix this ?
here is diagram
R5 (Area 0 with Authentication)
|
| Area 5
|
R7--------R8
Link between R7 and R8 is in Area 55
R7 and R8 is nssa
on R7, I configure nssa with area 55 nssa and I
redistribute connected interface to OSPF with
metric-type 1
on R8, I configure nssa with area 55 nssa
default-information no-summary
On R7, it be able to see default to R8
and on R8, it be able to see OSPF Route(N1) to R7
On R8 and R5, I am running virtual link
in R8, area 5 virtual-link (OSPF-ID R5) and
area 0 authentication message-digest
in R5, area 5 virtual-link (OSPF-ID R8) and
area 0 authentication message-digest
However, when I do show ip ospf database on R8
I just see type 7 LSA for injected connected route (no
type 5)
and obviously, it does not propagate to R5
any idea how to translate type 7 LSA to type 5 LSA ?
I check all OSPF virtual-link and it is up and get
full route and I even reload NSSA ABR, it did not
help
here is config and routing table
for R5
