4000 Router Series High Availability Command Reference

Parameters

value: Specifies the multi-hop detection time multiplier in the range of 3 to 50.

Usage guidelines

The detection time multiplier determines the maximum number of concurrent BFD control packets that can

be discarded.

Table 14 sh

ows the detection interval calculation methods.

[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 multi-hop 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 multi-hop BFD control packets is 1000 milliseconds.

Parameters

value: Specifies the minimum interval for receiving multi-hop BFD control packets, in milliseconds. The

value range for this argument is 30 to 10000.

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.
