7.20.9 Example for Configuring BGP GTSM
Networking Requirements
As shown in Figure 7-12, Switch A belongs to AS 10, and Switch B, Switch C, and Switch D
belong to AS 20. BGP is run in the network and BGP GTSM is configured to protect Switch B
against CPU-utilization attacks.

Configuration Roadmap
The configuration roadmap is as follows:
1. Configure OSPF on Switch B, Switch C, and Switch D to implement interworking in AS
20.
2. Set up an EBGP connection between Switch A and Switch B, and set up IBGP connections
between Switch B, Switch C, and Switch D through loopback interfaces.
