Configuring An Ospf Stub Area - HP MSR2000 series Configuration Manual

Configure summary route 10.0.0.0/8 on Switch B and advertise it:
5.
[SwitchB-ospf-1] asbr-summary 10.0.0.0 8
# Display the OSPF routing table of Switch A.
[SwitchA] display ip routing-table
Routing Tables: Public
Destination/Mask
10.0.0.0/8
11.2.1.0/24
11.2.1.2/32
127.0.0.0/8
127.0.0.1/32
The output shows that routes 10.1.1.0/24, 10.2.1.0/24, 10.3.1.0/24 and 10.4.1.0/24 are
summarized into one route 10.0.0.0/8.

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.
