Abstract: This application discloses a packet transmission method, a network device, and a system. After receiving a first packet, a first network device obtains a tunnel header corresponding to the first packet. The first network device encapsulates a tunnel header in an IPv6 header by encapsulating the IPv6 header in the first packet, to obtain a second packet. The first network device sends the second packet to a second network device, so that the second network device forwards the packet based on the tunnel header included in the IPv6 header. In this application, the IPv6 header is used to carry the tunnel header.

Abstract: In a packet processing method, a network device obtains a first packet. The network device determines a first index value based on address information of the first packet and a neural network model. The network device determines, from an action information table based on the first index value, action information corresponding to the first packet, where the action information table includes at least one entry, and each entry corresponds to an index value and a piece of action information. The network device processes the first packet based on the action information corresponding to the first packet.

Abstract: This application discloses a route processing method and a network device. The network device obtains a route prefix and autonomous system information associated with the obtained route prefix, where the associated autonomous system information includes to-be-verified autonomous system information. The network device verifies whether there is a match item in a route origin information base, where the match item includes the obtained route prefix and the to-be-verified autonomous system information; and determines, based on a verification result, whether to send the obtained route prefix. The network device verifies the autonomous system information associated with the to-be-sent route prefix before sending the route prefix. This reduces a possibility that the network device sends route information carrying incorrect autonomous system information, and reduces a possibility of causing an abnormal network flow direction.

Abstract: This application discloses a routing information sending method and apparatus. The method includes: receiving, by a first network node, routing information sent by a second network node, and determining the routing information corresponds to a tenant identifier; and then determining, by the first network node, that a third network node belongs to a tenant corresponding to the tenant identifier, and sending the routing information to the third network node in response to determining that the third network node belongs to the tenant corresponding to the tenant identifier.

Abstract: A method includes a first provider edge (PE) device sending, to a second PE device, a media access control (MAC) route learned from a customer edge (CE) device and a virtual local area network (VLAN) identifier, wherein the second PE device generates a MAC forwarding entry based on the MAC route and the VLAN identifier, where the MAC forwarding entry is used to directly forward, using the CE device, a packet whose destination MAC address is the CE device or a MAC address of a terminal device accessing the CE device. An outbound interface identifier included in the MAC forwarding entry is an identifier of an interface connected to the CE device.
