how does kolla configure br-ex?
I deployed using kolla/kolla-ansible 5.0.0 on one compute node and one control node.
How does kolla configure the br-ex bridge??? After deploying, I can see that there are three bridges br-int, br-tun, and br-ex by running ovs-vsctl show
But where is the ifcfg-br-ex
files?? Do I need to add the ifcfg-br-ex
? I am getting confused with things since openstack services are running within containers,. I am having uses with pinging the floating IP's and router in openstack and I think it is an issue with the br-ex.
I have added all the correct security groups so I know thats NOT the problem.
So I am trying to understand how much I am responsible for configuring the br-ex or does kolla do all that for me?
check /etc/kolla/neutron-openvswitch-agent/ml2_conf.in .in this file there is ovs tag which defines bridge mapping. each neutron service has ml2 file in it.br-ex is configured by kolla itself in network node
Ok thanks. I’m still a little confused though. I see br-int, br-tun, br-ex when I run the
ovs-vsctl show
in the openvswitchd container and it all looks correct but when I runnmcli d
orip a
br-int, br-tun, br-ex say they are unmanaged. Like in the output in the comment below. Why is that?br-ex openvswitch unmanaged br-int openvswitch unmanaged br-tun openvswitch unmanaged ovs-system openvswitch unmanaged
br-ex br-int and br-tun are supposed to have no ip address and are in down state after deployement.
