Combining with the characteristics of regional network of power dispatch data network, and according to the technology principle of the virtual private network BGP/MPLS VPN, the ways of implementing Border Gateway Protocol(BGP)and Multiprotocol Label Switching(MPLS)in OMNeT++ were analyzed respectively. A new solution to implement BGP/MPLS VPN for the simulation environment of OMNeT++ was presented which is consistent with the RFC standard for regional power dispatch data network. At last, it gives the measurement of BGP/MPLS VPN simulation in the actual scenario, which proved the feasibility of this solution.
