Abstract: A tunnel management method includes sending, by a head node of an end-to-end segment routing traffic engineering (SR-TE) tunnel, an operation, administration, and maintenance (OAM) packet to an intermediate node of the SR-TE tunnel, setting an outer label stack of the OAM packet to enable a stack bottom label to point to the intermediate node, receiving an identifying the OAM packet by an intermediate node, obtaining, by the intermediate node, OAM information related to a tunnel between the head node and the intermediate node of the SR-TE tunnel, and sending, by one or more intermediate nodes of the SR-TE tunnel, OAM information obtained by the intermediate nodes to a control management device.
