摘要：This application provides a packet transmission method and apparatus. Themethod includes: receiving, by a first transmission device, a first VXLAN packet sent by afirst service device through a first virtual extensible local area network VXLAN tunnel;determining, by the first transmission device, first egress information corresponding to a

first BD and a first destination media access control MAC address, based on a

correspondence between the first BD, the first destination MAC address, and the firstegress information; generating, by the first transmission device, a second VXLAN packetbased on the first VXLAN packet and the first egress information, where the secondVXLAN packet includes a second VNI and an Ethernet frame; and sending, by the firsttransmission device sends the second VXLAN packet to a second transmission devicethrough a second VXLAN tunnel. This application facilitates more flexible packettransmission.
