OSPF summary route advertising configuration example
Network requirements
As shown in Figure 164:
• Router A and Firewall are in AS 200, running OSPF.
• Router B, Router D, and Router C are in AS 100, running OSPF.
• An eBGP connection is established between Firewall and Router B. Router B is configured to
redistribute OSPF routes into BGP.
• Firewall is configured to redistribute BGP routes into OSPF. Firewall is configured with route
summarization and advertises only the summary route 10.0.0.0/8 to reduce Router A's routing
table size.
