<p>Provided are a method, aggregation device and system for implementing a continuity check, relating to the field of MPLS. The method includes: a communication network includes an access device, an aggregation device and an aggregation gateway device, wherein there is an access section between the access device and the aggregation device, there is an aggregation section between the aggregation device and the aggregation gateway device; and the communication network also includes a first connection and a second connection. The method includes: respectively running a continuity check on the access section of the first connection and on the second connection; when any connection in the first connection has failed, transmitting the connection identifier of the failed first connection to the aggregation gateway device, so that the aggregation gateway device carries out corresponding fault processing; and when the second connection has failed, transmitting a connection failure message to the access device through the first connection, so that the access device carries out corresponding fault processing.</p> |
