##       topology Linear behind Device Group1 and Mesh behind Device Group2     #
##    2. Enable Shared Risk Link Group(SRLG) in ISIS Emulated                   #
##       Router in both Device Group.                                           #

##       Router behind Device Group1 & with value 15 for all ISIS simulated     #
##       routers Router behind Device Group2 .                                  #

##       :true for emulated Router in both device group.                        #
##    7. Give Link Protection type Of Dedicated 1:1 and shared:true for all     #

##    10. On the fly uncheck "Enable SRLG"  emulated router in Device group2 &  #
##        check  "Enable SRLG" for all simulated Routers behind device group1   #
##    11. On the fly do change on Link type i.e  make enhanced:true and         #
