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: 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.
