draft-ietf-bfd-v4v6-1hop-05: BFD for IPv4 and IPv6 (Single Hop) 

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

Before configuring BFD detection modes, complete the following tasks: 

z 

Configure the network layer addresses of the interfaces so that adjacent nodes are reachable to 

each other at the network layer;  

z 

Configure the routing protocols that support BFD 

Follow these steps to configure BFD basic functions: 

Enter system view 

— 

Specify the mode for 
establishing a BFD session 

bfd session init-mode { active 
| passive } 

Optional 

active by default 

Enter interface view 

interface interface-type 
interface-number 

— 

Configure the minimum interval 
for transmitting BFD control 
packets 

bfd min-transmit-interval 
value 

Optional 

The value defaults to 400. 

Configure the minimum interval 
for receiving BFD echo packets 

bfd 
min-echo-receive-interval 
value 

Optional 

The value defaults to 400. 

Configure the minimum interval 
for receiving BFD control 
packets 

bfd min-receive-interval 
value 

Optional 

The value defaults to 400. 

Configure the maximum 
number of consecutive BFD 
packets that the remote device 
fails to receive from the local 
device before considering the 
BFD session down 

bfd detect-multiplier value 

Optional 

5 by default
