Configuring An Ospf Stub Area - HP 3600 v2 series Configuration Manual

Configuring an OSPF stub area

Network requirements
Figure 41 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).
Configure Area 1 as a stub area, reducing LSAs to this area without affecting route reachability.
