摘要： A method for managing a customer edge device includes: receiving, by a UNI set in a third-party operator network, an E-LMI packet sent by a VUNI set in a service provider network, where the VUNI is configured to manage a RUNI correlated with an EVC in the third-party operator network; converting, by the UNI, a unicast DMAC address in the E-LMI packet into a multicast DMAC address; and sending, by the UNI, the converted E-LMI packet to a CE device connected with the UNI. The E-LMI packet sent by the VUNI set in a service provider network may penetrate the third-party operator network, so that the management information of the service provider network can be transmitted to the CE device that is connected with the third-party operator network through the UNI.
