Configuring an OSPF Stub Area
Network requirements
The following figure shows an AS is split into three areas, where all switches run OSPF. AC and Switch
A act as ABRs to forward routing information between areas. Switch C acts as the ASBR to redistribute
routes (static routes).
It is required to configure Area 1 as a Stub area, reducing LSAs to this area without affecting route
reachability.

1) Configure IP addresses for interfaces (omitted).
2) Configure OSPF basic functions (refer to Configuring OSPF Basic Functions ).
3) Configure Switch C to redistribute static routes.
