Design and Implementation of a Highly Reliable Backbone Network Based on MPLS VPN
To meet the requirements for flexible expansion and secure,reliable network con-struction,a wide area multi-branch interconnection scheme based on MPLS VPN is designed.The de-ployment of various protocols such as ISIS,BGP,and MPLS on devices is discussed,analyzing the configuration processes in MPLS VPN technology,including the establishment of BGP peers,creation of VPN instances,distribution of MPLS labels,and transmission of VPNv4 private network routes.Experimental results show that the scheme improves network forwarding efficiency,ensures the secu-rity of enterprise private network route transmission,and satisfactorily meets the demands of enterprise network construction..
