#     On each port, it will create one topology of LDP dual stack router.      #
#     In each topology, there will be one device group and a network group.    #
#     The device group will simulate as a LDP dual stack router having LDP and #
#     LDPv6 interface over IPv4 and IPv6 stack respectively and a basic LDP    #
#     dual stack router connected to both IPv4 and IPv6 interface. The         #
#     transport connection preference in LDP router is set to IPv6.            #
#     The network groups consists of both IPv4 and IPv6 prefix pools.          #
#     Traffic is configured in between IPv6 prefix pools as end points.        #       
#                                                                              #
