Abstract: A packet processing method is disclosed. According to the method, a first network device receives a first packet sent by a second network device, where the first packet includes a first group identifier corresponding to a VPN on the second network device, a first source device corresponding to the first packet belongs to the VPN, and the first source device is connected to the second network device. The first network device obtains a second group identifier based on a destination address of the first packet, where the second group identifier corresponds to the VPN on a third network device, a first destination device corresponding to the destination address of the first packet belongs to the VPN, and the first destination device is connected to the third network device. The first network device processes the first packet based on the first group identifier and the second group identifier.

Abstract: A fault detection method, a network device, and a system are provided. The method includes: After a first network device receives, through a first forwarding path in an SR policy, a BFD packet that is sent by a second network device and that includes indication information of a SID list, the first network device determines, based on the indication information of the SID list, a second forwarding path that is reversely co-routed with the first forwarding path, and sends a response packet of the BFD packet to the second network device through the second forwarding path, so that the second network device can perform fault detection on the first forwarding path based on the response packet.
