4.14.3 Example for Configuring an OSPF NSSA Area

Networking Requirements
As shown in
three areas. SwitchA and SwitchB function as ABRs to forward routes between areas. SwitchD
functions as the ASBR to import external routes (static routes).
The requirement is to configure Area 1 as an NSSA area and configure SwitchC as an ASBR to
import external routes (static routes). The routing information can be transmitted correctly in
the AS.
