Configuring OSPF Route Redistribution

Network requirements
As shown in the following figure:
All the switches run OSPF, and the AS is divided into three areas.
Switch A and Switch B act as ABRs to forward routes between areas.
Switch C is configured as an ASBR to redistribute external routes (static routes). Routing
information is propagated properly in the AS.
