Abstract: A network system includes a first network device, a second network device, and a third network device. The first network device is configured to: obtain a first route advertisement message, where the first route advertisement message includes a first route prefix; and obtain a second route prefix based on the first route prefix, where the second route prefix corresponds to a first network slice, and the second route prefix is a subnet prefix of the first route prefix. The first network device advertises a second route advertisement message to the second network device, where the second route advertisement message includes the second route prefix.

Abstract: A packet processing method and apparatus, and a communication system are provided, and belong to the field of communication technologies. The method includes: After receiving an IPv6 packet including a first DOH, an intermediate node parses the first DOH based on a first policy, to obtain first information carried in the first DOH, and processes the IPv6 packet based on the first information. The IPv6 packet includes an RH and the first DOH is located after the RH, or the IPv6 packet does not include an RH. In this application, an intermediate node that performs parsing to obtain information carried in an IPv6 extension header may be flexibly specified, to resolve a problem that a parsing rule of an extension header of an existing IPv6 packet is not flexible enough. This application is used for packet processing.
