#    This script intends to demonstrate how to use NGPF PIM API.               #
#                                                                              #
#    1. It will create 2 PIM topologies and Ipv6 Prefix Pool under             #
#       the network group(NG)                                                  #
#    2. Start the pim protocol.                                                #
#    3. Retrieve protocol statistics.                                          #
#    4. Retrieve protocol learned info.                                        #
#    5. Modify the Range type from "*G" to "SG" in the First and Second PIM    #
#       router.And apply changes On The Fly (OTF)                              #
#    6. Retrieve protocol learned info again and notice the difference with    #
#       previously retrieved learned info.                                     #
