It works...
Try reloading your ABR between the NSSA area and the other area...
also make sure a routers in that area agree on NSSA (config it on each router i
n the area)
I have this config
r1---------------------r5--------------------------r7
r1 and r5 are connected via NSSA r5 and r7 are area 0
I am redistributing external at r1..

When I inject an external route to a OSPF NSSA router, only the NSSA routers
are seeing the route. The non-NSSA routers are not getting the external
route. Does anyone know why this is happening ? I thought the NSSA ASBR
would have converted the type-7 route into a type-5 route and add it to the
ospf table. Not the case here. Any insight would be much appreciated.
Thanks,
Phillip
