#    It uses two Ixia ports. BGP peers and routes are configured on both       #
#    ports.  Streams are generated using ixnetwork traffic_generator           #
#    Traffic statistics are collected for each flow.                           #
#    Flow rates are updated while the traffic is running with mode             #
#    dynamic update.
