Original Abstract Submitted

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.
