Configuration Roadmap
The configuration roadmap is as follows:
1. Configure basic BGP functions on each switch.
2. Configure MED attributes to control the route selection.
3. Enable BFD on Switch A and Switch B.
Data Preparation
To complete the configuration, you need the following data:
l Router IDs and AS numbers of Switch A Switch B, and Switch C
l Peer IP address detected by BFD
l Minimum interval for sending BFD control packets, minimum interval for receiving BFD
control packets, and local detection multiplier
