Abstract: Embodiments of this application disclose a method and an apparatus for transmitting a virtual private network segment identifier (VPN SID), and a network device. An egress node sends a VPN SID corresponding to the egress node to each node in a network, and indicates to each node to store the VPN SID of the egress node. In this way, both an ingress node and each intermediate node can sense and store the VPN SID. When a VPN service needs to be provisioned, because each node stores the VPN SID of the egress node, it is possible for each node to associate the VPN SID with a forwarding entry of the VPN service to be provisioned in a forwarding table, to implement VPN route convergence. In addition, for a of a VPN corresponding to the VPN SID and that is sent by a user side, both the ingress node and the intermediate node can guide forwarding of the packet based on a locally stored VPN SID, to implement VPN service-level control.

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 loop avoidance communications method, where a first provider edge (PE) device sends a first identifier to a second PE device through a first interface, the first PE device receives, through the first interface, a data packet from the second PE device including the first identifier. Then, the first PE device determines that a second interface associated with the first identifier is in a faulty state. In response to the determining that the second interface is in the faulty state, the first PE device avoids sending the data packet to the second PE device through the first interface, where the first PE device connects to a customer edge (CE) device using the second interface.
