The # # transport connection preference in LDP router is set to IPv6. # # The network groups consists of both IPv4 and IPv6 prefix pools. # # Traffic is configured in between IPv6 prefix pools as end points. # # # # 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 FEC 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. Stopallprotocols. # # # # Ixia Software: # # IxOS 6.90 EA # # IxNetwork 7.50 EA # # # ################################################################################ import os import sys import time
