# Description:                                                                  #
#    This script intends to demonstrate how to use NGPF RSVPTE API              #
#    About Topology:                                                            #
#       Within topology both Label Switch Router(LSR) and Label Edge Router(LER)#
#    are created. LSR is emulated in the front Device Group(DG), which consists #
#    of both OSPF as routing protocol as well as RSVPTE-IF for Label            # 
#    Distribution Protocol. The chained DG act as LER, where RSVP-TE LSPs are   #
#    configured. Unidirectional L2-L3 Traffic from Ingress to Egress is created.#
#         Script Flow:                                                          #
#        Step 1. Configuration of protocols.                                    #
#    Configuration flow of the script is as follow:                             #
#             i.      Adding of OSPF router                                     #
#             ii.     Adding of Network Topology(NT)                            #
#             iii.    Enabling of TE(Traffic Engineering)                       #
#             iv.     Adding of chain DG                                        #
#             v.      Adding of RSVPTE-IF                                       #
#             vi.     Adding of RSVP-TE LSPs within chain DG                    #
#        Step 2. Start of protocol                                              #
#        Step 3. Protocol Stat display                                          #
#        Step 4. Learned Info display                                           #
#        Step 5. On The Fly(OTF) change of protocol parameter.                  #
#        Step 6. Again Learned Info display to see OTF changes take place       #
#        Step 7. Configuration L2-L3 Traffic                                    #
#        Step 8. Apply and Start of L2-L3 traffic                               #
#        Step 9. Display of L2-L3  traffic Stats                                #
#        Step 10.Stop of L2-L3 traffic                                          #
#        Step 11.Stop of all protocols                                          #
