Problems solved by technology

[0004] In view of this, this application provides a label distribution method and device to solve the problem that when some devices play the role of P equipment in MPLS networking, because they do not have the function of supporting P equipment, they cannot normally forward VPN message; or, the problem that its original function based on routing and forwarding cannot be realized

Abstract

The present application provides a label allocation method and device, which are applied to MPLS equipment, and the method includes: determining a VPN label to be allocated for a VPN route to be diffused, and the VPN label corresponds to a VRF; when the VPN route is diffused, Allocating the VPN label to the VPN route, so that when a packet carrying the VPN label is received, the packet is routed and forwarded in the VRF corresponding to the VPN label. Applying the above method can solve the problem that when some devices play the role of P devices in the MPLS network, they cannot forward VPN packets normally because they do not have the function of supporting P devices; The problem of the function that can only be realized by routing and forwarding.

Description

technical field [0001] The present application relates to the technical field of network communication, and in particular to a label allocation method and device. Background technique [0002] MPLS (Multiprotocol Label Switching, multi-protocol label switching) L3VPN (Layer3VirtualPrivate Network, three-tier virtual private network) is a service provider VPN (Virtual Private Network, virtual private network) solution based on PE (Provider Edge, service provider Edge) L3VPN technology, which uses BGP (Border Gateway Protocol, Border Gateway Protocol) to publish VPN routes on the service provider's backbone network, and uses MPLS to forward VPN packets on the service provider's backbone network. The MPLS L3VPN network architecture model consists of three parts: CE (Customer Edge, user edge) equipment, PE equipment, and P (Provider, service provider) equipment. Among them, the CE device is the edge device of the user network, which can be a router or switch, or a host; the PE ...
