Table 17 Detection interval calculation method
Mode Detection interval
Control packet mode BFD session in
asynchronous mode
Detection time multiplier of the receiver × actual
packet sending interval of the receiver
Control packet mode BFD session in demand
mode
Detection time multiplier of the sender × actual
packet sending interval of the sender
Examples
# Configure the multihop detection time multiplier as 6.
<Sysname> system-view
[Sysname] bfd multi-hop detect-multiplier 6
bfd multi-hop min-receive-interval
Use bfd multi-hop min-receive-interval to configure the minimum interval for receiving multihop BFD
control packets.
Use undo bfd multi-hop min-receive-interval to restore the default.
Syntax
bfd multi-hop min-receive-interval value
undo bfd multi-hop min-receive-interval
Default
The minimum interval for receiving multihop BFD control packets is 1000 milliseconds.

Parameters
value: Specifies the minimum interval for receiving multihop BFD control packets, in the range of 10 to
10000 milliseconds.
Usage guidelines
When the packet sending rate of the peer end exceeds the packet receiving capability (minimum control
packet receiving interval) of the local end, the peer end dynamically adjusts the BFD control packet
sending interval to the minimum control packet receiving interval of the local end.
Examples
# Configure the minimum interval for receiving multihop BFD control packets as 500 milliseconds.
<Sysname> system-view
[Sysname] bfd multi-hop min-receive-interval 500
bfd multi-hop min-transmit-interval
Use bfd multi-hop min-transmit-interval to configure the minimum interval for transmitting multihop BFD
control packets.
