A first network device sends a request packet to a second network device or a network management device, where the request packet is used to request to confirm whether the second network device has an iFIT capability; and the first network device receives a confirmation packet sent by the second network device or the network management device, where the confirmation packet includes confirmation information used to confirm whether the second network device has the iFIT capability.

Method for confirming in-situ flow information telemetry capability and device

A method and a device for multicast packet processing are disclosed. The method includes: A first network device obtains a data packet; and the first network device generates a first multicast packet and a second multicast packet based on the data packet. The first multicast packet includes first iFIT information and a first multi-level flow identifier. The second multicast packet includes the first iFIT information and a second multi-level flow identifier. The first multi-level flow identifier and the second multi-level flow identifier are different, to identify different forwarding paths of the generated first multicast packet and second multicast packet respectively. In the method, in a point-to-multipoint multicast data flow transmission scenario, a plurality of multicast data flows can be identified, to perform iFIT detection on each of the plurality of data flows, so as to implement packet loss and delay detection, path restoration, and the like for the multicast data flows.

Multicast packet processing method and device

This application provides an authentication method and related device and system. The method includes sending, by a first network device, a first next-hop resolution protocol (NHRP) registration request message to the second network device, where the first NHRP registration request message is used to request the second network device to perform digital certificate authentication on the first network device, and the first NHRP registration request message includes first PKI certificate information. The method may further include receiving, by the first network device, a first NHRP registration reply message indicating that the digital certificate authentication performed by the second network device succeeds. In this way, authentication is performed between a spoke device and a hub device using a PKI certificate. This helps reducing authentication workload and improving authentication security.

Authentication method, device, and system

A communications connection detection method includes sending, by a first network node, a detection request packet to a second network node, where the detection request packet is used to detect whether the first network node and the second network node are in a connected mode, deleting, by the first network node, a next hop resolution protocol (NHRP) table between the first network node and the second network node when the first network node determines that the first network node does not receive a detection response packet sent by the second network node.
