Abstract: A route advertisement method, a network device, and a computer storage medium are provided, and pertain to the field of communication technologies. According to this application, an EVPN SRv6 route advertisement packet is extended to carry pseudo-wire identification information of an L2VPN PW between a first network device and a second network device, to help find, based on the pseudo-wire identification information, a forwarding entry associated with the L2VPN PW, and further process the forwarding entry associated with the L2VPN PW, thereby evolving an MPLS forwarding-based L2VPN VPWS into an SRv6 forwarding-based EVPN VPWS, or evolving an MPLS forwarding-based L2VPN VPLS into an SRv6 forwarding-based EVPN VPLS. In addition, the MPLS forwarding-based L2VPN VPWS or VPLS can be evolved into another type of EVPN SRv6 network.

Abstract: A packet transmission method, device, and system for network technologies are disclosed. A first network device receives, by using a first VPLS instance a packet to be sent to a user-side device connected to the second network device. The first network device forwards, based on an association relationship between the first VPLS instance and the first VPWS instance, the packet to a second VPWS instance in the second network device by using the first VPWS instance. A VPLS instance is associated with a VPWS instance in the first network device. A packet that is received by using the VPLS instance and that is to be sent to a user-side device can be forwarded by using the associated VPWS instance, so that pressure to learn a MAC address for packet transmission is reduced, and forwarding performance of the system is ensured.

Abstract: A packet processing method and a network device are provided. The method is applied to a network system, and the network system includes a first network device and a plurality of network devices separately connected to the first network device. The method includes: The first network device groups the plurality of network devices into a plurality of groups based on a service, where each of the plurality of groups includes at least one network device. The first network device determines one or more groups in the plurality of groups, and forwards packets of the service to one or more of the plurality of network devices in the one or more groups. In present application, a mode for forwarding the packets of the service can be flexibly selected according to a service requirement, to better meet the service requirement.
