Abstract: A route processing method, a device, and a system, where the method includes: a network virtualization edge (NVE) device set including at least two NVE devices includes a common Virtual Extensible Local Area Network (VXLAN) Tunnel Endpoint (VTEP) address. The common VTEP address is used to identify a common VTEP, and the common VTEP is deployed on each NVE device in the NVE device set. In addition, each NVE device in the NVE device set includes a VTEP address, and the VTEP address is used to identify a VTEP included in a corresponding NVE device. An NVE device in the NVE device set establishes a VXLAN tunnel between the NVE devices in the NVE device set based on a VTEP address and the common VTEP address using an inclusive multicast Ethernet tag (IMET) route.

Abstract: A packet processing method and apparatus, and a communication system are provided, and belong to the field of communication technologies. The method includes: After receiving an IPv6 packet including a first DOH, an intermediate node parses the first DOH based on a first policy, to obtain first information carried in the first DOH, and processes the IPv6 packet based on the first information. The IPv6 packet includes an RH and the first DOH is located after the RH, or the IPv6 packet does not include an RH. In this application, an intermediate node that performs parsing to obtain information carried in an IPv6 extension header may be flexibly specified, to resolve a problem that a parsing rule of an extension header of an existing IPv6 packet is not flexible enough. This application is used for packet processing.

Abstract: A negotiation mode processing method and an intelligent network device relate to the field of communications technologies, and used to improve application flexibility of the intelligent network device. The method includes determining, by an intelligent network device, that a physical layer (PHY) receives an auto-negotiation configuration stream from a network device connected to the PHY, and changing a negotiation mode of another PHY in the intelligent network device from a non-auto-negotiation mode to an auto-negotiation mode. The auto-negotiation configuration stream indicates that the device sending the auto-negotiation configuration stream is in the auto-negotiation mode. In this way, the application flexibility of the intelligent network device can be improved, and further improves communication quality of the network device.
