#        Step 1. Configuration of protocols.                                    #
#    Configuration flow of the script is as follow:                             #
#             i.      Adding OSPF router.                                       #
#             ii.     Adding Network Topology(NT).                              #
#             iii.    Adding chain DG.                                          #
#             iv.     Adding BGP over loopback.                                 #
#             v.      Adding EVPN VXLAN over BGP                                #
#             vi.     Adding MAC Cloud with associated IPv4 Addresses           #
#        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.                                         #
