An OSPF NSSA
None
A not-so-stubby area (NSSA) is just like a stub area, but shares routing information with an external network that is using a different routing protocol. In other words, it is a stub area with an ASBR router. The remote network becomes an area to your OSPF network, eliminating the need to implement the different routing protocol within the OSPF network. See the OSPF section in Chapter 9 for more information.
area-id
The area to which this command applies.
no-redistribution
