Hi,

I saw there are two commands binding logical ports to hypervisor in OVN tutorial scripts

 

ovs-vsctl add-port br-int lport1 -- set Interface lport1 external_ids:iface-id=sw0-port1    [1]

 

ovn-sbctl lport-bind sw0-port3 fakechassis   [2]

 

Is there any difference between them? Thanks.

Yes, ovn-controller normally does this automatically. The case where ovn-sbctl does it is because we are simulating a fake other hypervisor and manually do a step that ovn-controller on that hypervisor would have done. 

Thanks for your explanation. Does it mean in real deployment (i.e., no fake chassis), I should use "ovs-vsctl add-port br-int" on the hypervisor to bind lport?
