Configuring OSPF to advertise a summary route

Network requirements
As shown in
• Switch A and Switch B are in AS 200, which runs OSPF.
Switch C, Switch D, and Switch E are in AS 100, which runs OSPF.
•
An eBGP connection is established between Switch B and Switch C. Switch B and Switch C are
configured to redistribute OSPF routes and direct routes into BGP and BGP routes into OSPF.
Switch B is configured with route summarization and advertises only the summary route 10.0.0.0/8 to
reduce Switch A's routing table size.
