摘要： Embodiments of this application provide a method, an apparatus, and a system for deploying a service. In this method, a controller creates a service instance corresponding to a service, and creates, in the service instance, a first network instance and a second network instance that correspond to the service. The first network instance is a network instance corresponding to a first device, and the first network instance includes a device identifier of the first device. The second network instance is a network instance corresponding to a first cloud provider edge PE, and the second network instance includes a device identifier of the first cloud PE. The first cloud PE is for connecting to the first cloud. In this method, a procedure of deploying a virtual cloud private network service is simplified, the service deployment is simplified, and efficiency and accuracy of the service deployment are improved.

摘要： A method, a system, and an apparatus for extranet networking of a multicast Virtual Private Network (VPN) are disclosed in the present invention. The method includes: establishing a multicast tunnel to a source VPN multicast instance and a multicast tunnel interface (MTI) connected to the multicast tunnel according to an added Share-Group address of a source VPN; sending an encapsulated Protocol Independent Multicast (PIM) protocol message to the MTI, forwarding the encapsulated PIM protocol message in a public network, and making the source VPN multicast instance generate a public network multicast data message of a Share-Group of the source VPN according to the encapsulated PIM protocol message; and decapsulating the received public network multicast data message of the Share-Group of the source VPN, and obtaining multicast data from the source VPN multicast instance. The present invention reduces the resource occupation of a router system, and alleviates the network load.

摘要： This application discloses a communication method and a related apparatus. The method includes: A first network device obtains first link layer topology information corresponding to a first network slice; the first network device obtains second link layer topology information corresponding to a second network slice; the first network device determines, based on the first link layer topology information and the second link layer topology information, that a link layer topology of the second network slice is included in a link layer topology of the first network slice; the first network device receives network layer topology information that is of the first network slice and that is sent by a second network device; and the first network device determines network layer topology information of the second network slice based on the second link layer topology information and the network layer topology information of the first network slice. Network layer topology information of one network slice is multiplexed on a plurality of network slices, so that a quantity of routes used by a network device to advertise the network layer topology information can be reduced, and resource costs can be reduced.
