Abstract: Embodiments of this application provide a route advertisement method, a network device, and a system. A first network device receives a route advertisement packet from a second network device, where the route advertisement packet includes a common field and a variable field, the common field carries a common part of N segment routing over internet protocol version 6 SRv6 segment identifiers SIDs, the variable field carries a variable part of a first SRv6 SID in the N SRv6 SIDs, the N SRv6 SIDs correspond to a first prefix, and N is a positive integer greater than or equal to 2. The first network device obtains the N SRv6 SIDs based on the common part and the variable part of the first SRv6 SID. The first network device generates a first route, where the first route includes the first prefix and the N SRv6 SIDs.

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.

Abstract: This application provides a communication method and apparatus. The method includes: A first communication apparatus receives a first EVPN MAC route from a second communication apparatus, where the first EVPN MAC route carries a first MAC address and a first VNI. The first communication apparatus generates a second EVPN MAC route based on the first EVPN MAC route, where the second EVPN MAC route carries the first MAC address and a first SID that is of the first communication apparatus and that corresponds to the first VNI. The first communication apparatus sends the second EVPN MAC route to a third communication apparatus. This application implements interconnection between a VXLAN and an SRv6 network.

Abstract: Embodiments of this application disclose a segment routing over internet protocol version 6 (SRv6)-based communication method and a related apparatus. A layer 2 gateway generates an Ethernet virtual private network instance (EVI) media access control (EVI-MAC route), where the EVI-MAC route includes an Ethernet virtual private network instance segment identifier (EVI SID), the EVI SID is an SRv6 SID applied for by an EVI from the layer 2 gateway, and a MAC address carried in the EVI-MAC route does not include a MAC address of each host in the EVI. The layer 2 gateway advertises the EVI-MAC route to a layer 3 gateway. After the layer 2 gateway advertises the EVI-MAC route to the layer 3 gateway, the layer 3 gateway does not receive a MAC address of a host from the layer 2 gateway.
