Release Information

Statement introduced in JUNOS Release 8.0.

detection-time threshold and transmit-interval threshold options introduced in JUNOS Release 8.2.

Support for logical routers introduced in JUNOS Release 8.3.

no-adaptation statement introduced in JUNOS Release 9.0.

Description

Configure bidirectional failure detection timers.

Options

detection-time threshold milliseconds—Configure a threshold. When the BFD session detection time adapts to a value equal to or greater than the threshold, a single trap and a single system log message are sent.
minimum-interval milliseconds—Configure the minimum intervals at which the local router transmits a hello packet and then expects to receive a reply from the neighbor with which it has established a BFD session.
minimum-receive-interval milliseconds—Configure only the minimum interval at which the local router expects to receive a reply from a neighbor with which it has established a BFD session.
multiplier number—Configure the number of hello packets not received by a neighbor that causes the originating interface to be declared down.
no-adaptation—Configure BFD sessions not to adapt to changing network conditions. We recommend that you not disable BFD adaptation unless it is preferable not to have BFD adaptation enabled in your network.
transmit-interval threshold milliseconds—Configure a threshold. When the BFD session transmit interval adapts to a value greater than the threshold, a single trap and a single system log message are sent. The interval threshold must be greater than the minimum transmit interval.
transmit-interval minimum-interval milliseconds—Configure only a minimum interval at which the local router transmits hello packets to a neighbor.
version—Specify the BFD version to detect.

Usage Guidelines
