Abstract

The application provides an E-Tree implementation method and device based on RFC 8317 and a communication device. In a remote communication scenario, when a PE device receives a packet sent by a CE device, the PE device obtains the ingress interface logical port information of the logical port of the CE device, obtains the logical port corresponding to the destination MAC address based on the MAC address forwarding table, and then obtains the egress interface logical port information. The encapsulation strategy is determined according to the ingress interface logical port information and the egress interface logical port information, and the packet is encapsulated based on the encapsulation strategy and then sent out. The scheme is enabled by the logical port, the logical port can be expanded based on the demand on the basis of the physical port, can be applicable to various network environments, and the packet is encapsulated based on the ingress interface and the egress interface logical port information, so that the PE device can perform packet forwarding based on the encapsulation information in the outgoing direction, to realize E-Tree isolation.
