The other network group has mac pools which is # # simulated as CE router and also is used as traffic end point. # # # # Script Flow: # # 1. Configuration of protocols as described in topology. # # 2. Start the LDP protocol. # # 3. Retrieve protocol statistics. # # 4. Retrieve protocol learned info. # # 5. Change LDP PW/VPLS labels & apply change on the fly # # 6. Retrieve protocol learned info again. # # 7. Configure L2-L3 traffic. # # 8. Start the L2-L3 traffic. # # 11. Retrieve L2-L3 traffic stats. # # 12. Stop L2-L3 traffic. # # 13. Stop all protocols. # # # ################################################################################ import os import sys import time def assignPorts (ixNet, realPort1, realPort2) : chassis1 =
