摘要： Embodiments of this application disclose a segment routing over internet protocol version 6 SRv6-based communication method and a related apparatus. The method may be used in a campus network, and the method includes: 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. In this way, MAC routing pressure on the layer 3 gateway is effectively reduced, so that the layer 3 gateway can establish communication connections with more hosts, thereby effectively expanding a network capacity.

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

摘要： 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. According to the method, a length of the route advertisement packet is reduced, a bandwidth occupied by the route advertisement packet is reduced, and route advertisement efficiency is improved.

摘要： A packet transmission method, device, and system are disclosed, and pertain to the field of network technologies. The system includes a first network device in a VPLS network and a second network device in a VPWS network. The first network device determines, based on a destination address carried in a received first packet, a virtual port corresponding to the destination address in a VPLS instance of the first network device, and sends the first packet to a second VPWS instance in the second network device based on the virtual port, where the virtual port is used to indicate a first VPWS instance in the first network device, and the second VPWS instance and the first VPWS instance are VPWS instances used to bear a same service. In this application, according to an interconnection solution in which a VPLS instance and a VPWS instance are deployed on the first network device of the system, pressure on the second network device of the system to learn a MAC address for packet transmission can be reduced, and forwarding performance of the network system can be ensured.
