Usage guidelines

If you enable the echo packet mode for a BFD session in which control packets are sent and the session comes up, BFD does the following:

• Periodically sends echo packets to detect link connectivity.

• Decreases the control packet receiving rate at the same time.

# Enable the echo packet mode on VLAN-interface 11.

[Sysname] interface vlan-interface 11
