OSPF NSSA area configuration example
Network requirements
Figure 166 shows an AS is split into three areas, where all routers run OSPF. Router A and Router B act
as ABRs to forward routing information between areas.
Configure Area 1 as an NSSA area, and configure Router C as an ASBR to redistribute static routes into
the AS.

Configuration procedure
