z One segment can belong to only one area and you must specify each OSPF
interface to belong to a particular area.
4.4 OSPF Area Attribute Configuration
Area partition in OSPF reduces the number of LSAs in the network and enhances
OSPF scalability. To further reduce routing table size and the number of LSAs in some
non-backbone areas on the edge of the AS, you can configure these areas as stub
areas.
A stub area cannot import any external route. For this reason the concept of NSSA area
is introduced. Type7 LSAs can be advertised in an NSSA area. Type7 LSAs are
generated by ASBRs of the NSSA area, and will be transformed into AS-external LSAs
whey reaching ABRs in the NSSA area, which will then be advertised to other areas.
After area partition, the OSPF route updates between non-backbone areas are
exchanged by way of the backbone area. Therefore, OSPF requires that all the
