Description

Enable loss-threshold-tlv transmission.

During a unified ISSU, the control plane may go down for several seconds and cause CFM continuity check packets to get dropped. This may cause the remote maintenance endpoint (MEP) to detect a connectivity loss and mark the MEP as down. To keep the MEP active during a unified ISSU, the loss threshold TLV communicates the minimum threshold value the receiving MEP requires to keep the MEP active. The receiving MEP parses the TLV and updates the loss threshold value, but only if the new threshold value is greater than the locally configured threshold value. You can control the transmission of the loss threshold TLV in continuity check messages PDUs. The convey-loss-threshold statement specifies that the loss threshold TLV must be transmitted as part of the continuity check messages. If the statement is not specified, continuity check messages transmit this TLV only when a unified ISSU is in progress.
