BGP path selection configuration

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.
