Configuration method of cross-domain MPLS VPN based on double MCE
Ting Yan, Wenhua Wu, Lei Li, Wenjia Xie · 2022
There are some inherent defects in the traditional VPN technology, which makes many needs of customers unable to be met when networking, and the implementation is relatively complex. Dual MCE cross domain MPLS VPN connects CE devices to PE devices of multiple same service providers, solves the address space overlap problem of the traditional VPN technology, and enhances the redundancy of the network. Starting from the actual operator case, this paper analyzes the needs and configures OSPF, MPLS, BGP/mbgp, routing strategy and other complex protocols on the equipment. The experimental results show that this method can well solve the shortcomings of traditional VPN technology, and summarizes the general operation methods with the flow chart, which provides a reference for better configuration in the future.
