bfd-liveness-detection (EVPN Node Detection)

Syntax

Hierarchy Level

Description

Configure Bidirectional Forwarding Detection (BFD) timers and options for EVPN node detection.

Options

no-adaptation

Disable the BFD adaptation. Include this statement to prevent the BFD sessions from adapting to changing network conditions.

detection-time

Mandatory

  • threshold milliseconds — Configure a threshold for the adaptation of the BFD session detection time. When the detection time equals or exceeds the threshold, a single trap and a single system log message are sent.

    • Range: 1 through 255000

inline-disable

Disable inline mode for this BFD session

minimum-interval milliseconds

Configure the minimum transmit and receive interval the local device transmits to, and expects a reply from, the BFD neighbor. Optionally, you can specify the minimum receive interval separately using the minimum-receive-interval option. Or you can use the transmit-interval statement's minimum-interval and minimum-receive-interval options.

  • Range: 1 through 255000

minimum-receive-interval milliseconds

Configure the minimum interval the local device expects to receive a reply from the BFD neighbor. Optionally, instead of using this statement, you can configure the minimum receive interval using the minimum-interval statement.

  • Range: 1 through 255000

multiplier number

Configure the number of BFD packets not received before declaring the BFD peer interface down.

  • Default: 3

  • Range: 1 through 255

neighbor

Configure the interface address of the BFD neighbor.

pdu-size

Configure the BFD transport protocol payload size

  • Default: 24

  • Range: 24 through 9000

transmit-interval
  • minimum-interval milliseconds — Configure a minimum interval after which the local routing device transmits hello packets to a neighbor. Optionally, instead of using this statement, you can configure the minimum transmit interval using the minimum-interval statement.

    • Range: 1 through 255000

  • threshold milliseconds — Configure 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. The interval threshold must be greater than the minimum transmit interval.

version

BFD protocol version number

  • 0—BFD version 0 (deprecated)

  • 1—BFD version 1

  • automatic—Choose BFD version automatically
