It will create 2 mLDP topologies: 1 Ingress with Root Range configured # # and another Egress with Leaf Range. # # 2. Configure Root Ranges with Source Endpoint. # # 3. Configure Leaf Ranges with Multicast Destination Endpoint. # # 4. Start the ldp protocol. # # 5. Retrieve protocol statistics. # # 6. Retrieve protocol learned info. # # 7. Change label and LSP Count per Root & apply change on the fly # # 8. Retrieve protocol learned info again and notice the difference with # # previouly retrieved learned info. # # 9. Configure IPv4 & IPv6 L2-L3 traffic. # # 10. Retrieve L2-L3 traffic stats. # # 11. Stop L2-L3 traffic. # # 12. Stop all protocols. # ################################################################################ import os import sys import time def assignPorts (ixNet, realPort1, realPort2) : chassis1 =
