Configuring BFD basic functions
Before configuring BFD basic functions, configure the network layer addresses of the interfaces so that
adjacent nodes are reachable to each other at the network layer.
After a BFD session is established, the two ends negotiate BFD parameters, including minimum sending
interval, minimum receiving interval, initialization mode, and packet authentication, by exchanging
negotiation packets. They use the negotiated parameters without affecting the session status.
Configuring echo packet mode
The echo packet mode cannot be configured on a device with uRPF enabled. For more information about
uRPF, see Security Configuration Guide.
To configure echo packet mode:
