Abstract

The invention provides a method for generating a route. The method is applied to an SRv6 network. The method comprises the following steps: first network equipment receives a first notification message from second network equipment, wherein the first notification message comprises a network slice identifier, the first notification message indicates an association relationship between identification information of the network slice and an IPv6 address prefix of the second network device, and the network slice identifier is used for identifying one network slice; and the first network equipmentgenerates a routing forwarding entry for the IPv6 address prefix of the second network device according to the association relationship between the network slice identifier and the IPv6 address prefixof the second network device. And network slicing and resource isolation in the SRv6 network can be realized.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method for generating a route, a network device and a system. Background technique [0002] Network Slicing is a form of virtualization that allows multiple logical networks to run on top of a shared physical network infrastructure. That is to say, based on a shared physical network, corresponding network slices (or virtual networks) are cut out through virtualization technology to meet the differentiated needs of users. The resources of each virtual network slice are logically isolated, independent, and independent of each other. [0003] Segment Routing is the inheritance and innovation of Internet Protocol (IP) routing technology, and has unique advantages in realizing network virtualization and network programmability. The data plane of the SR adopts two modes: Multi-Protocol Label Switching (Multi-Protocol Label Switching, MPLS) or Internet Communication Pr...
