If you enable the echo packet mode for a BFD session in which control packets are sent and the session goes up, BFD periodically sends echo packets to detect link connectivity and decrease control packet receive rate. The default setting is 400 milliseconds. The default setting is 400 milliseconds. The default setting is 5. To configure control packet mode for multi-hop detection: Step Command Remarks 1.

4.
Configure the authentication
mode for single-hop control
packets.
bfd authentication-mode simple

|
plain
plain-string
}
By default, single-hop BFD packets
are not authenticated.
5.
Enable the Demand BFD
session mode.
bfd demand enable
By default, the BFD session is in
Asynchronous mode.
6.
Enable the echo packet mode.
bfd echo enable
By default, the echo packet mode
is disabled.
If you enable the echo packet
mode for a BFD session in which
control packets are sent and the
session goes up, BFD periodically
sends echo packets to detect link
connectivity and decrease control
packet receive rate.
7.
Configure the minimum
interval for transmitting
single-hop BFD control
packets.
bfd min-transmit-interval
value
The default setting is 400
milliseconds.
8.
Configure the minimum
interval for receiving
single-hop BFD control
packets.
bfd min-receive-interval
value
The default setting is 400
milliseconds.
9.
Configure the single-hop
detection time multiplier.
bfd detect-multiplier
value
The default setting is 5.
