Configuring control packet mode
To configure control packet mode for single-hop detection:
Step Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Specify the mode for
establishing a BFD session.
bfd session init-mode { active |
passive }
By default, active is specified.
3.
Enter interface view.
interface interface-type
interface-number
N/A
4.
Configure the authentication
mode for single-hop control
packets.
bfd authentication-mode simple
key-id { cipher cipher-string | 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 1000
milliseconds.
8.
Configure the minimum
interval for receiving
single-hop BFD control
packets.
bfd min-receive-interval value
The default setting is 1000
milliseconds.
9.
Configure the single-hop
detection time multiplier.
bfd detect-multiplier value
The default setting is 5.
To configure control packet mode for multi-hop detection:
Step Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Specify the mode for
establishing a BFD session.
bfd session init-mode { active |
passive }
By default, active is specified.
3.
Configure the authentication
mode for multi-hop BFD
control packets.
bfd multi-hop authentication-mode
simple key-id { cipher cipher-string
| plain plain-string }
By default, no authentication is
performed.
4.
Configure the destination port
number for multi-hop BFD
control packets.
bfd multi-hop destination-port
port-number
The default setting is 4784.
