Design And Implementation Of BGP/MPLS VPN In Domestic Multi Branch Company

With the rapid development of Chinese enterprises,the demand for network scale is also increasing.In particular,the network conditions needed by the domestic multi branch companies are getting higher and higher,and the traditional way of network formation has not been able to keep up with the development speed of the enterprise itself.So in order to cater to the trend and direction of network development,the internal network of enterprise needs to combine the technology of MPLS(MultiProtocol Label Switching,multi protocol label switching)and BGP(Border Gateway Protocol,boundary gateway protocol)to form a fast deployment,high scalability,and easy to maintain BGP/MPLS VPN network.This article takes the LF retail enterprise as the research object,combines the actual situation of the enterprise,optimizes the overall structure of its internal network,and carries out the detailed design and implementation of the scheme.The main work of this paper is as follows.(1)Through the research on the current situation of the enterprise network and the traditional way of establishing the domestic network,this paper analyzes the shortcomings of the traditional enterprise private network,which has the inflexibility of increasing the network architecture nodes and the low utilization of the resources.Then through the comparison and analysis of the advantages and disadvantages of three different network construction methods,combined with the actual situation of the domestic multi branch company,the best way to fit the network of this type of enterprise is synthetically analyzed.(2)Therefore,in view of the above problems,this paper proposes to use MPLS technology and BGP technology to form and optimize the internal private network of domestic multi branch enterprises,in order to solve the problems in the original network of the enterprise.Taking the domestic multi branch company LF nut retail enterprise as the research object,we deeply understand the current situation of the enterprise and the existing problems of complex operation and maintenance,traffic congestion and low scalability,and make a comprehensive analysis and summary on the demand of network application,such as QoS and multi service.(3)Before designing and setting up the scheme,this paper thinks about the design process,puts forward the problems of the suitability of the enterprise network and information and communication,how to distinguish the information of each point of the enterprise and the security of the whole network,and thinks out the corresponding solutions to ensure the feasibility of the later case.After setting up the final construction target and outline design of the network,the network construction scheme suitable for the SH,HZ,SZ,CQ and other points of the multi branch enterprise is detailed.The planning covers the IP address of each point of the distribution enterprise,the RD/RT numeric setting and the related planning of the BGP routing protocol.(4)The implementation is strictly carried out according to the content of the scheme.After the implementation,six performance tests,such as the neighbor's establishment,connectivity and the forwarding path of the label,are carried out to verify the implementation effect one by one.The data show that the optimized LF enterprise network can solve the existing problems in the original network and achieve the goal of the project setting.
