Configuring BFD basic functions

The BFD basic functions configuration is the basis for configuring BFD for other protocols.

Configuration prerequisites

Before configuring BFD basic functions, complete the following tasks:
Configure the network layer addresses of the interfaces so that adjacent nodes are reachable to
•
each other at the network layer
Configure the routing protocols that support BFD
•

Configuration procedure

To configure BFD basic functions:
To do...
• Enter system view
• Specify the mode for
establishing a BFD session
•
Configure the destination port
number for multi-hop BFD
control packets
• Configure the source IP
address of echo packets
• Enter interface view
• Configure the minimum
interval for receiving BFD
echo packets
• Configure the minimum
interval for transmitting BFD
control packets
Use the command...
system-view
bfd session init-mode { active |
passive }
bfd multi-hop destination-port
port-number
bfd echo-source-ip ip-address
interface interface-type interface-
number
bfd min-echo-receive-interval
value
bfd min-transmit-interval value
158
Remarks
—
Optional
active by default
Optional
4784 by default
Optional
The source IP address should not
be on the same network segment
as any local interface's IP
address; otherwise, a large
number of ICMP redirect packets
may be sent from the peer,
resulting in link congestion
