Configuring OSPF to advertise a summary route at the CLI
Network requirements
As shown in Figure 269 :
• Router A and SecPath are in AS 200, running OSPF.
• Router B, Router C, and Router D are in AS 100, running OSPF.
An EBGP connection is established between SecPath and Router B. SecPath and Router B are configured
to redistribute OSPF routes and direct routes into BGP and BGP routes into OSPF.
SecPath is configured with route summarization and advertises only the summary route 10.0.0.0/8 to
reduce Router A's routing table size.
