Configuring an NSSA Area
To configure an NSSA area, the following conditions are required: The OSPF protocol is
run on routers, and the area to be configured is a stub area or a non-backbone area.
Create a stub area with an ASBR. Routers in this area receive routing messages from an
external AS through the ASBR. External routing messages from other areas are blocked.
Because some routers do not support the NSSA configuration and cannot recognize Type
7 LSAs, the protocol defines that the ABR on the NSSA converts Type 7 LSAs generated
within the NSSA to Type 5 LSAs, and then advertises the LSAs. At this time, the advertiser
of the LSAs is changed to the ABR. This is called routing translation. Using this method,
routers outside the NSSA area are not required to support the NSSA configuration.
To configure an NSSA area on the ZXR10 5900E, perform the following steps:
