Network requirements
• In the figure below, all switches run BGP. eBGP connections are between Switch A and Switch B, and between
Switch A and Switch C. iBGP connections are between Switch B and Switch D, and between Switch C and
Switch D.
• OSPF is the IGP protocol in AS 200.
• Configure the routing policies. Switch D should use the route 1.0.0.0/8 from Switch C as the optimal route.
