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: Embodiments of this application disclose a traffic forwarding processing method and a device. The method includes: A first network device receives a first packet that is from a second network device and that includes a MAC address of a destination device and a color identifier of the MAC address. The first network device obtains an address of a third network device, where the destination device is multi-homed to the second network device and the third network device. The first network device determines a first forwarding policy based on the address of the third network device and the color identifier, and forwards, to the third network device according to the first forwarding policy, traffic destined for the MAC address.
