Here is the scenario...
R1, R2, R3, R4.
R1 is an ABR to area 0. R1 is also attached to area 1.
R2 is an internal router to area 1
R3 is an ABR to area 1 and area 2. Since area 2 is not
attached directly to area 0, area 1 is a transit area,
and there is a virtual link between R1 and R3.
R4 is an internal router to area 2
OSPF has synchornised, all routes are available every
Now area 2 should not get any external route. So area
2 was configured as a stub area. Now the requirement
is, that the ethernet of R4 (x.x.x.x) should be
advertised into OSPF without using network statement.
So I used redistribute command in R4. But since area
2 is a stub area, this is not possible. So inorder to
use redistribute command on R4, area 2 was configured
R4 gives this route to R3. R3 has this route as ON2.
Now this route should have been converted as type 5
LSA and should appear in R2 and R1. But the route
never appears even in database of R2 and R1.
Looks like, NSSA routes are not converted into Type 5
lsas and exchanged to routers which are in a transit
