BIT-FORWARDING INGRESS ROUTER BIT-FORWARDING ROUTER AND OPERATION ADMINISTRATION AND MAINTENANCE DETECTION METHOD

摘要

The present application relates to the field of multicast networks, and provides a bit forwarding entrance router, a bit forwarding router and an OAM test method. The first BRF receives an OAM request packet from the BFIR; The first BFR determines that the destination BFR corresponding to the OAM request packet is the first BFR according to the OAM request packet; The first BFR acquires a first OAM response packet according to the ID of the BFIR, and transmits the first OAM response packet to the BFIR. According to the method and apparatus provided in the embodiment of the present application, when a failure occurs during transmission of a multicast packet, a problem that the BFIR cannot diagnose or handle a transmission failure can be solved, and the OAM packet is used to assist in connectivity testing. And enables testing of multiple BFERs.
