# Description:                                                                 #
#    This script intends to demonstrate how to use NGPF ISISL3 API.            #
#                                                                              #
#    1. It will create 2 ISISL3 topologies, each having an ipv4 & ipv6 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 the isisL3 protocol.                                             #
#    3. Retrieve protocol statistics.                                          #
#    4. Retrieve protocol learned info.                                        #
#    5. Enable the IsisL3 simulated topologies ipv4 & ipv6 noderoutes, which   #
#       was disabled by default and apply change on the fly.                   #
#    6. Retrieve protocol learned info again and notice the difference with    #
#       previously retrieved learned info.                                     #
#    7. Configure L2-L3 traffic.                                               #
#    8. Configure IPv4 application traffic.[application Traffic type is set    #
#       using variable "trafficType". "ipv4ApplicationTraffic" for ipv4 profile#
#       and "ipv6ApplicationTraffic" for ipv6 profile.                         #
#       Note: IPv4 & IPv6 both could not be configured in same endpoint set.   # 
#    9. Start the L2-L3 traffic.                                               #
#   10. Start the application traffic.                                         #
#   11. Retrieve Application traffic stats.                                    #
#   12. Retrieve L2-L3 traffic stats.                                          #
#   13. Stop L2-L3 traffic.                                                    #
#   14. Stop Application traffic.                                              #
#   15. Stop all protocols.                                                    #
#                                                                              #
