Configuring Control Packet Mode - HP 5900 Series Configuration Manual

Step
2. Configure the source IP
address of echo packets.
3. Enter interface view.
4. (Optional.) Set the minimum
interval for receiving BFD
echo packets.
5. (Optional.) Set the single-hop
detection time multiplier.

Configuring control packet mode

To configure control packet mode for single-hop detection:
Step
1. Enter system view.
2. Specify the mode for
establishing a BFD session.
3. Enter interface view.
4. Configure the authentication
mode for single-hop control
packets.
5. Enable the Demand BFD
session mode.
Command
•
Configure the source IP address
of echo packets:
bfd echo-source-ip ip-address
•
Configure the source IPv6
address of echo packets:
bfd echo-source-ipv6
ipv6-address
interface interface-type
interface-number
bfd min-echo-receive-interval
value
bfd detect-multiplier value
Command
system-view
bfd session init-mode { active |
passive }
interface interface-type
interface-number
bfd authentication-mode simple
key-id { cipher cipher-string | plain
plain-string }
bfd demand enable
122
Remarks
Use either command.
By default, no source IP address is
configured for echo packets.
The source IP address cannot be on
the same network segment as any
local interface's IP address.
Otherwise, a large number of
ICMP redirect packets might be
sent from the peer, resulting in link
congestion.
The source IPv6 address of echo
packets can only be a global
unicast address.
N/A
By default, the minimum interval for
receiving BFD echo packets is 400
milliseconds.
The default setting is 5.
Remarks
N/A
By default, active is specified.
To establish a session for BFD
MAD, the system always operates
in active mode. For more
information about BFD MAD, see
IRF Configuration Guide.
N/A
By default, single-hop BFD packets
are not authenticated.
By default, the BFD session is in
Asynchronous mode.
