Release Information

Statement introduced in Junos OS Release 8.2.

Support for BFD authentication introduced in Junos OS Release 9.6.

Description

Specify the transmit interval for the bfd-liveness-detection statement. The negotiated transmit interval for a peer is the interval between the sending of BFD packets to peers. The receive interval for a peer is the minimum time that it requires between packets sent from its peer; the receive interval is not negotiated between peers. To determine the transmit interval, each peer compares its configured minimum transmit interval with its peer's minimum receive interval. The larger of the two numbers is accepted as the transmit interval for that peer.

Options

minimum-interval milliseconds— Configure the minimum interval at which the local routing device transmits hello packets to a neighbor with which it has established a BFD session. Optionally, instead of using this statement at this hierarchy level, you can configure the minimum transmit interval using the minimum-interval statement at the bfd-liveness-detection hierarchy level.

Note

The threshold value specified in the threshold statement must be greater than the value specified in the minimum-interval statement for the transmit-interval statement.

Range: 1 through 255,000 milliseconds

threshold milliseconds— Specify the threshold for the adaptation of the BFD session transmit interval. When the transmit interval adapts to a value greater than the threshold, a single trap and a single system message are sent.

Range: 0 through 4,294,967,295 (2³² – 1)

Note

The threshold value specified in the threshold statement must be greater than the value specified in the minimum-interval statement for the transmit-interval statement.

Required Privilege Level

routing—To view this statement in the configuration.

routing-control—To add this statement to the configuration.
