Re: Type-4 LSA and NSSA

Hi,

let me again cite RFC 3101, page 5:
"Also an NSSA's border routers never originate Type-4 summary-LSAs for the
NSSA's AS boundary routers, since Type-7 AS-external-LSAs are never flooded
beyond the NSSA's border."

As Type-4 describes how to reach the sender of Type-5, the ABRs towards
other areas will flood Type-4 LSAs.
In Narbiks example, this would be the ABR between A2 and A0.
