The MPLS_TUNNEL_BDI alarm indicates defects in the backward direction of a tunnel. This alarm is reported when a BDI packet is received at the receive end, indicating that the forward tunnel is faulty.


Alarm Severity Alarm Type


Communication alarm



Impact on the System

The services on the transmit channel at the local end are affected.

Possible Causes

The possible cause of the MPLS_TUNNEL_BDI alarm is as follows:

  • The opposite NE detects that the tunnel is faulty.


  1. On the U2000, check whether there are hardware-related alarms at the local end, such as HARD_BAD and LSR_NO_FITED. If yes, clear these alarms. Then check whether the MPLS_TUNNEL_BDI alarm is cleared.
  2. If the alarm persists, check whether an optical fiber or a cable between the local NE and the opposite NE is damaged. If yes, replace the faulty optical fiber or cable.
