#    This script intends to demonstrate how to use NGPF LDP API.               #
#                                                                              #
#    1. It will create 2 LDP topologies, each having an ipv4 prefixpools       #
#        and loopback device group behind the network group(NG) with           # 
#       loopback interface on it. A loopback device group(DG) behind network   # 
#       group is needed to support applib traffic.                             #
#    2. Start the ldp protocol.                                                #
#    3. Retrieve protocol statistics.                                          #
#    4. Retrieve protocol learned info.                                        #
#    5. Disbale/Enable the ldp FECs and change label & apply change on the fly #
#    6. Retrieve protocol learned info again and notice the difference with    #
#       previouly retrieved learned info.                                      #
#    7. Configure L2-L3 traffic.                                               #
#    8. Configure application traffic.                                         #
#    9. Start the L2-L3 traffic.                                               #
#   10. Start the application traffic.                                         #
#   11. Retrieve Appilcation traffic stats.                                    #
#   12. Retrieve L2-L3 traffic stats.                                          #
#   13. Stop L2-L3 traffic.                                                    #
#   14. Stop Application traffic.                                              #
