> When,  VpcPhysicalTopologyConfigCommand, OvsVpcRoutingPoli     cyConfigCommand are sent
by management server, scripts that populate the open flow rules to the bridge are configuring
rules sequentially one after other. this no effective and probability error prone as well
if a rule fails to program there is no revoking.
> To avoid such situation first create a file, that has all the updates and use the ovs-ofctl
option to replace the bridge rules through the file.
