5. Configure route summarization:
# Configure route summarization on Firewall to advertise a single route 0.0.0.0/8.
[Firewall-ospf-1] asbr-summary 10.0.0.0 8
# Display the IP routing table on Router A.
[RouterA] display ip routing-table

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 a single route 10.0.0.0/8.
OSPF stub area configuration example
Network requirements
• Enable OSPF on all routers, split the AS into three areas.
• Configure Router A and Router B as ABRs to forward routing information between areas.
• Configure Router C as the ASBR to redistribute static routes.
• Configure Area 1 as a stub area to reduce LSAs advertised without influencing reachability.

Configuration procedure
1. Configure IP addresses for interfaces. (Details not shown.)
2. Configure basic OSPF (see "Basic OSPF configuration example").
3. Configure route redistribution:
# Configure Router C to redistribute stati
c routes.
<RouterC> system-view
[RouterC] ip route-static 3.1.2.1 24 10.5.1.2
