Abstract: This application discloses a packet sending method, a network device, and a computer storage medium, and pertains to the field of communications technologies. The method includes: generating, by a network device, a first packet, where the first packet includes a field used to indicate a first protocol, the first packet further includes a field carrying data of the first protocol, and a protocol followed by the first packet is different from the first protocol; and sending, by the network device, the first packet to a peer network device. Because the protocol followed by the first packet is different from the first protocol, regardless of which protocol the first protocol is specifically, the data of the first protocol may be exchanged by using the first packet. In other words, this application provides a general protocol, to transmit the data of the first protocol. This improves packet sending flexibility.

Abstract: Embodiments of this application disclose a route advertisement method, a route loop check method, and a device, so as to resolve a route loop problem in a network, and improve reliability of service packet transmission. The route advertisement method includes the following steps: A first network device receives a first route advertisement message, where a first field of the first route advertisement message includes a device identifier, and routing information included in the first route advertisement message comes from a device corresponding to the device identifier. The first network device generates a second route advertisement message based on the first route advertisement message, where a second field of the second route advertisement message includes the device identifier, and the first field and the second field are different fields. The first network device sends the second route advertisement message to a second network device.
