Hi David,

Are you using devstack? Would you please explain me more details about 
your issue? I have the similar kind of questions before, but I am not sure 
we met the same.
Firstly, how many NICs are you using for OpenStack?
If you are using flat dhcp mode, no matter you set br100 or other ethernet 
to it, they are both fine as Vish explained.
Please remember do not let your fix ip network and floating ip network 
connect to the same bridge or ethernet/NIC.

Best wishes.

Re: [Openstack] About floating ip interface config






Yes, this can work. This is the default setup in devstack. Generally for 
production you would want to split to separate interfaces or vlans for 
security reasons, but it does work to put everything on one interface like 
that.

Hi all
 
Can floating IP interface also use br100 ? I mean flag 
--public_interface=br100 , and if use flat dhcp mode .
And the openstack environment is multi-host :
Three host , one controller , two compute node .
