Abstract: A first network device includes a processor and a memory having instructions stored thereon that, when executed by the processor, cause the first network device to: obtain a first virtual private network (VPN) route sent by a second network device. The first VPN route includes first identification information that uniquely identifies a first VPN instance in the second network device. The first network device is also caused to generate a second VPN route according to a second VPN instance accessing a third network device and the first VPN route. The second VPN route carries second identification information and routing information of the first VPN route. The second identification information uniquely identifies the second VPN instance in the third network device. The first identification information is different from the second identification information. The first network device is further caused to send the second VPN route to the third network device.

Abstract: A network device creates a virtual border gateway protocol (BGP) peer and the BGP peer is enabled all BGP capability data configured in the network device. A BGP monitoring protocol (BMP) module of the network device acquires the enabled BGP capability by using a BGP message. According to the solution of the embodiment, the network device obtains all BGP capabilities configured in the network device and sends all the BGP capabilities to a monitoring server, so that the monitoring server can fully understand actual capability supported by the entire network, further providing an effective basis for deployment of and decision on the entire network.

Abstract: The technology of this application relates to a packet transmission method and a communication apparatus. The method includes a validation device obtaining an address prefix from a sending device. The validation device sends a response packet to the sending device, where the response packet indicates usage status information of the address prefix at a receiving device. In this manner, the validation device may enable, by using the response packet, the sending device to learn of the usage status information of the address prefix at the receiving device, so that the sending device processes an exception of the address prefix, to help improve accuracy of source address validation, achieve a zero false positive, and minimize a false negative.
