Configuring BFD basic functions
The BFD basic function configuration is the basis for configuring BFD for other protocols.
Configuration prerequisites
Before configuring BFD basic functions, complete the following tasks:
• Configure the network layer addresses of the interfaces so that adjacent nodes are reachable to
each other at the network layer.
• Configure the routing protocols that support BFD.
Configuration procedure
To configure BFD basic functions:
