3.10.2 Configuring an OSPF Stub Area
I. Network requirements
The following figure shows an AS is split into three areas, where all switches run OSPF.
Switch A and Switch B act as ABRs to forward routing information between areas.
Switch D 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.

Network diagram for OSPF Stub area configuration
III. Configuration procedure
1)
Configure IP addresses for interfaces (omitted).
2)
Configure OSPF basic functions (refer to
Configuring OSPF Basic Functions
).
3)
Configure Switch D to redistribute static routes.
[SwitchD] ip route-static 200.0.0.0 8 null 0
[SwitchD] ospf
[SwitchD-ospf-1] import-route static
[SwitchD-ospf-1] quit
# Display ABR/ASBR information on Switch C.
[SwitchC] display ospf abr-asbr
