Abstract: Embodiments of this application disclose a route advertisement method, a route loop check method, and a device, so as to resolve a route loop problem in a network, and improve reliability of service packet transmission. The route advertisement method includes the following steps: A first network device receives a first route advertisement message, where a first field of the first route advertisement message includes a device identifier, and routing information included in the first route advertisement message comes from a device corresponding to the device identifier. The first network device generates a second route advertisement message based on the first route advertisement message, where a second field of the second route advertisement message includes the device identifier, and the first field and the second field are different fields. The first network device sends the second route advertisement message to a second network device.

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.
