Problems solved by technology

Therefore IP Ping / traceroute tools cannot be used to diagnose all major aspects of L3VPN services
[0007] As can be seen, there is as yet no proper diagnostic tool to verify the integrity of VPN business entities and RFC 4364-based Border Gateway Protocol (BGP) / Multi-Protocol Label Switching (Multi-Protocol Label Switching, MPLS) IP VPN The data path of the business grouping of the business

Embodiment Construction

[0023] Preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although preferred embodiments of the invention are shown in the drawings, it should be understood that the invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0024] Before describing the basic idea of ​​the present invention, review the L3VPN service model to introduce some necessary concepts and terms. figure 1 A schematic diagram showing a general deployment model of RFC 4364-based BGP / MPLSL3VPN.

[0025]Generally, distributed L3VPN services can be regarded as a group of virtual routing and forwarding (Virtual Routing and Forwarding, VRF) instances, which are interconnected through service transmiss...

Abstract

The present invention discloses a method and apparatus for L3VPN (Virtual Private Network) service diagnosis. The apparatus is located in a first PE (Provider Edge) and includes a construction unit, a transmitting unit and a receiving unit; the construction unit is configured to construct an L3VPN service response request message; the transmitting unit is configured to transmit the L3VPN service response request message to a second PE; and the receiving unit is configured to receive an L3VPN service response reply message from the second PE; and the L3VPN service response request message contains a target service entity TLV and is used for specifying an L3VPN service entity which should respond to the L3VPN service response request message.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, relates to a method and device for L3VPN service diagnosis. Background technique [0002] Currently, existing tools that can be used to diagnose Layer 3 virtual private network (L3 Virtual Private Network, L3VPN) services include the label switching path (Label Switch Path, LSP) Ping / route tracking tool specified in RFC 4379, or the RFC The virtual circuit connectivity verification (Virtual Circuit Connectivity Verification, VCCV) tool specified in 5085, or the traditional IP Ping / trace route tool applied in the context of an L3VPN instance. While each can be used to diagnose some aspects of L3VPN traffic, none of them is sufficient to diagnose all major aspects of L3VPN traffic: the status of L3VPN business entities, the mode of service label allocation and the total number of service labels allocated for L3VPN business entities, and the L3VPN The data path of the busine...
