#         Within topology both Provider Edge(PE) and Provider(P) Routers are created.#
# created.P router is emulated in the front Device Group(DG), which consists of both #
# OSPF as routing protocol as well as Basic LDP sessions for Transport Label         #
# Distribution Protocol. The chained DG act as PE Router, where LDP Extended Martini #
# is configured for VPN Label distribution protocol.Bidirectional L2-L3 Traffic is   #
# configured in between two CE cloud is created.                                     #

#     1. Configuration of protocols.                                                 #
#    Configuration flow of the script is as follow:                                  #
#         i.    Adding of OSPF router.                                               #
#         ii.   Adding of Network Cloud.                                             #

#         iv.   Adding of LDP(basic session) on Front DG                             #
#         v.    Adding of LDP Extended Martini(Targeted sess.) over chained DG.      #
#         vi.   Adding of LDP PW/VPLS Tunnel over LDP Extended Martini.              #
#    2. Start the ldp protocol.                                                      #
#    3. Retrieve protocol statistics.                                                #
#    4. Retrieve protocol learned info.                                              #
#    5. Disable/Enable the ldp FECs and change label & 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. Start the L2-L3 traffic.                                                     #

#   10. Stop L2-L3 traffic.                                                          #
