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

summarized into a single route 10.0.0.0/8.
661BOSPF stub area configuration example
1440BNetwork requirements
• Enable OSPF on all devices, 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.

1441BConfiguration procedure
1. Configure IP addresses for interfaces. (Details not shown.)
2. Configure basic OSPF (see "2605HBasic OSPF").
3. Configure route redistribution:
# Configure Router C to redistribute static routes.
