[ovs-discuss] multiple controller for a given OVS

[Mohammad Banikazemi]

Can an OVS be set to have more than one controller such that if one
controller fails another controller can be used by the switch?
If yes, how do I do that? Can I specify multiple controllers by using
theset-controller option of ovs-vsctl for this purpose or there are other
mechanisms to be used?

I have not been able to get a concrete answer to this question and have
seen conflicting answers to similar questions.

Thanks.

No. OVS supports multiple controllers but it always connects to all
of them, there is no notion of "primary" and "secondary".

Does this mean that all controlled equal and can control ovs in same time?
How can I add two controllers to ovs bridge?

Yes, they can do that.
