6.5 Configuring OSPFv3 NSSA Areas

Configuring a non-backbone area on the border of an AS as an NSSA does not transmit routes
learned from other areas in the AS but imports AS external routes. This reduces bandwidth and
storage resource consumption on the router.
6.5.1 Before You Start
Before configuring OSPFv3 NSSA areas, familiarize yourself with the usage scenario, complete
the pre-configuration tasks, and obtain the data required for the configuration.
Applicable Environment
An NSSA allows the transmission of Type 7 LSAs, which are generated by ASBRs in an NSSA.
The Type 7 LSAs converting into Type 5 LSAs in the NSSA and advertised to other areas.
