desired-minimum-transmit-interval number
Description

The minimum interval between transmission of BFD control packets

This value is advertised to the peer, however the actual interval used is specified by taking the maximum of desired-minimum-transmit-interval and the value of the remote required-minimum-receive interval value. This value is specified as an integer number of microseconds.

    When a BFD session runs over a series of path segments, this error code indicates that a subsequent path segment (i.e., one in the transmit path between the source and destination of the session) has failed.

  • ADMIN_DOWN

    The BFD session has been administratively disabled by the peer

  • REVERSE_CONCATENATED_PATH_DOWN

    A segment on the reverse path between destination and source has failed

    In the case that a BFD session is running over a series of path segments, this error code indicates that a path segment on the reverse path (i.e., in the transmit direction from the destination to the source of the session) has failed.

desired-minimum-transmit-interval number

Description

The minimum interval between transmission of BFD control packets

This value is advertised to the peer, however the actual interval used is specified by taking the maximum of desired-minimum-transmit-interval and the value of the remote required-minimum-receive interval value. This value is specified as an integer number of microseconds.

detection-multiplier number

Description

The number of packets that must be missed to declare this session as down

The detection interval for the BFD session is calculated by multiplying the value of the negotiated transmission interval by this value.

Description

The minimum interval between received BFD control packets that this system should support

This value is advertised to the remote peer to indicate the maximum frequency (i.e., minimum inter-packet interval) between BFD control packets that is acceptable to the local system. This value is specified as an integer number of microseconds.
