# Objective - FtOpSoRtPerfFn032 : Performance measurement for BGP Session Failover case
# Measure time taken for the traffic ( corresponding to BGP routes ) to resume fully
# (i.e RX rate = TX rate) after the BGP session flaps ( i.e BGP session goes down and then comes up
# This is triggered using "clear ip bgp * " CLI command ).
