#    This script intends to demonstrate how to use NGPF BGP API.               #
#                                                                              #
#    1. It will create 2 BGP topologies, each having an ipv4 network           #
#       topology 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 BGP protocol.                                                    #
#    3. Retrieve protocol statistics.                                          #
#    4. Enable IPv4 Learned Information on the fly                             #
#    5. Retrieve protocol learned information                                  #
#    6. Configure L2-L3 traffic.                                               #
#    7. Configure application traffic.                                         #
#    8. Start the L2-L3 traffic.                                               #
#   9. Start the application traffic.                                          #
#   10. Retrieve Appilcation traffic stats.                                    #
#   11. Retrieve L2-L3 traffic stats.                                          #
#   12. Stop L2-L3 traffic.                                                    #
#   13. Stop Application traffic.                                              #
