Configuring BFD basic functions
The BFD basic function 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:
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 }
Optional.
active by default.
3.
Configure the destination port
number for multi-hop BFD
control packets.
bfd multi-hop
destination-port
port-number
Optional.
4784 by default.
4.
Configure the source IP
address of echo packets.
bfd echo-source-ip
ip-address
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.
5.
Enter interface view.
