7.20.7 Example for Configuring a BGP Confederation
Networking Requirements
As shown in Figure 7-10, several Switches run BGP in AS 200. To reduce the number of IBGP
connections, divide AS 200 into three sub-ASs, namely AS 65001, AS 65002, and AS 65003.
In addition, IBGP connections are set up between the three Switches in AS 65001.
