Multicast domain on E-Government MPLS VPN

The technology of MD multicasting and its application on E-Government MPLS VPN are studied. MD can easily be implemented on E-Government MPLS network. Using MD multicasting method, every site on PE belongs to the same VPN is added to one multicasting domain; these sites can send and receive packets across service provider network. The realization of MD multicasting is only little changes on the original network and the configuration is simple. With this method, Provincial E-Government MPLS VPN with MD multicasting is realized and tested.
