Abstract: A first network device includes a processor and a memory having computer readable instructions stored thereon that, when executed by the processor, cause the first network device to obtain a Flow Specification (FlowSpec) rule with redirect indication information. The redirect indication information includes identification information identifying a first virtual private network (VPN) instance configured on a second network device. The indication information also includes instructions for the second network device to redirect data stream matching the FlowSpec rule to the first VPN instance. The first network device is also caused to advertise the FlowSpec rule with the redirect indication information to the second network device.

Abstract: A segment routing device receives a first packet from a first network. A first packet header of the first packet includes a segment list. The segment list includes a plurality of sequentially arranged identifiers. The identifiers include a first-type identifier and a plurality of second-type identifiers. Network devices or links identified by the first-type identifier and the second-type identifier are respectively on the first network and a second network. A type of the first network is different from a type of the second network. The segment routing device encapsulates a second packet header for the first packet to form a second packet. The second packet header includes the plurality of second-type identifiers. The segment routing device sends the second packet to the second network.

Abstract: A data packet detection method, a device, and a system are disclosed. The method includes: receiving first control information sent by a controller; receiving a first data packet sent by a previous-hop network device of a first network device, where the first data packet includes first detection information, and the first detection information includes a first detection node identifier, a first sequence number, and first collection information; determining, based on the first collection information, first collected data corresponding to the first collection information, and updating the first detection node identifier; and sending, to a next-hop network device of the first network device, the first data packet carrying the updated first detection information. This implements information telemetry on a data packet on a transmission path.

Abstract: Embodiments of the present disclosure provide a routing control method, network device, and controller. The method may include the network device obtaining a route suppression request. The method may also include determining the second routing entry. Furthermore, the method may include setting a state of the second routing entry to a non-delivery state that is used to indicate that the second routing entry does not need to be delivered to a forwarding table. In the method, the network device may have a first routing entry and a second routing entry, an address prefix of the first routing entry is a first address prefix, an address prefix of the second routing entry is a second address prefix, a network segment to which the second address prefix belongs is a subset of a network segment to which the first address prefix belongs, and a mask in the second address prefix is greater than a mask in the first address prefix.
