Abstract: The present disclosure provide a packet processing method, a related apparatus, and an NVO3 network system. A first NVE receives a first packet sent by a first CE, where the first packet includes a MAC address of the first CE and a VLAN ID; the first NVE determines a VNI of the first CE according to an inbound interface of the first packet and the VLAN ID; the first NVE performs NVO3 encapsulation on the first packet to obtain an NVO3 encapsulated first packet, where the NVO3 encapsulated first packet includes the VNI of the first CE, and a source IP address in an NVO3 header of the NVO3 encapsulated first packet is a first shared VTEP IP address shared by the first NVE and a second NVE; and the first NVE forwards the NVO3 encapsulated first packet to a remote NVE.

Abstract: The application provides a multicast communications method and an aggregation switch, which can implement on-demand replication of multicast traffic. The method includes: an aggregation switch (AGG) acquires a multicast group address link state protocol data unit (GM LSP) packet sent by an access switch (ACC); the AGG compares multicast join information in the GM LSP packet with multicast join information stored in the AGG, to obtain a comparison result, and the AGG updates the multicast join information stored in the AGG according to the comparison result. The AGG generates a preset-protocol packet by using changed multicast join information in the comparison result according to a preset format, where the preset-protocol packet is an Internet Group Management Protocol (IGMP) packet or a Protocol Independent Multicast (PIM) packet. The AGG sends the preset-protocol packet to a first multicast router.

Abstract: This application provides a packet processing method and a network device. A third network device is multi-homed to a first network device and a second network device, the first network device is configured with a first physical MAC address and a virtual MAC address, the second network device is configured with a second physical MAC address and the virtual MAC address, and the virtual MAC address is used to forward a user data packet to a network side. The method includes: a first network device receives a protocol packet from a third network device, where the protocol packet includes the second physical MAC address; and the first network device forwards the protocol packet to the second network device based on the second physical MAC address. Thus, the protocol packet can be normally forwarded without special configuration on a server, so that a cumbersome configuration process is avoided.

Abstract: The present invention provides a packet forwarding method and apparatus, and a data center network. The data center network includes two tenant end systems, a local management function, and a network virtualization edge. The local management function sends, to the network virtualization edge, a packet to which a label is added and that is sent by a tenant end system, and the network virtualization edge determines, according to the label, a virtual overlay network identifier corresponding to the tenant end system, adds the virtual overlay network identifier to the packet, performs tunnel encapsulation on the packet to which the virtual overlay network identifier is added, and sends a packet that is after the tunnel encapsulation to another network virtualization edge.
