Configuring BFD basic functions 

Before configuring BFD basic functions, configure the network layer addresses of the interfaces so that 
adjacent nodes are reachable to each other at the network layer. 
After a BFD session is established, the two ends negotiate BFD parameters, including minimum sending 

interval, minimum receiving interval, initialization mode, and packet authentication, by exchanging 

negotiation packets. They use the negotiated parameters without affecting the session status. 

Configuring echo packet mode 

Step Command 

Remarks 

1.

 

Enter system view. 

system-view 

N/A 

2.

 

Configure the source IP 
address of echo packets. 

•

 

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

 

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.
