Abstract

A tunnel switching method, device and switch, the method comprising: setting the class identifier of a service route in a tunnel protection group as a first class identifier, the tunnel protection group comprising a first tunnel and a second tunnel; determining a redirection rule for the service route according to the first class identifier; and switching the service route from the first tunnel to the second tunnel according to the redirection rule and the tunnel information of the second tunnel. The method solves the problem in the relevant art of overlong time delay caused by respectively switching each service route during three-layer overlay protection, thus reducing the time delay of service route switching.

Description

technical field [0001] The present invention relates to the communication field, in particular to a tunnel switching method, device and switch. Background technique [0002] Multi-Protocol Label Switching (MPLS for short) Layer 3 Virtual Private Network (L3VPN for short) is a service provider VPN solution based on Provider Edge (Provider Edge, short for short). PE) L3VPN technology, which uses Border Gateway Protocol (BGP for short) to advertise VPN routes on the service provider backbone network, and uses MPLS to forward VPN packets on the service provider backbone network. [0003] MPLS L3VPN has flexible networking mode, good scalability, and can easily support MPLS Quality of Service (QoS for short) and MPLS Traffic Engineering (Traffic Engineering, TE for short), so it has been applied more and more . [0004] The MPLS L3VPN model consists of three parts: customer edge (Customer Edge, referred to as CE) equipment, PE equipment and service provider (Provider, referred ...
