It will create 2 ISIS topologies, topology1 will have a simulated # # 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. # # 3. Give SRLG count 2 with value 5 and 6 for ISIS Emulated router # # Router in both Device Group. # # 4. Give SRLG count 1 with value 10 for all ISIS simulated routers # # Router behind Device Group1 & with value 15 for all ISIS simulated # # routers Router behind Device Group2 . # # 5. Enable Link Protection in ISIS Emulated Router in both Device Group # # 6. Give Link Protection type Of Extra traffic,Unprotected and Dedicated # # :true for emulated Router in both device group. # # 7. Give Link Protection type Of Dedicated 1:1 and shared:true for all # # simulated Router behind both device group. # # 8. Start protocol. # # 9. Retrieve protocol statistics. # # 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 # # unprotected:false for emulated router in Device group1 & disable"Enable# # Link Protection" for first 2 simulated Routers behind device group2 # # # # 12.
