Open Stack

Hi

I built OpenStack environment using OPNFV.
I started the instance on the compute node and confirmed the connection 
success.
I implemented IDS on my instance.
I want to do port mirroring other traffic to instances, but it does not 
go well.
Succeeded to add flow entry to br-int and mirror it to linux bridge.
I checked other traffic on inport of linux bridge with tcpdump.
However, I do not understand how to set up linux bridge.
I would appreciate hearing from you.
