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.
Examples
# Enable the echo packet mode on VLAN-interface 11.
<Sysname> system-view [Sysname] interface vlan-interface 11 [Sysname-Vlan-interface11] bfd echo enable
