Description Numan Siddique 2019-04-12 13:47:33 UTC 
Description of problem:
Suppose if there is a logical port - lport1 with [MAC, IP] configured but it is not bound to any chassis (because there is no corresponding ovs port created in any chassis) and if any VIF sends a GARP with the MAC of lport1, then ovn-controller on that chassis should bind this logical port.

Please see the BZ - https://bugzilla.redhat.com/show_bug.cgi?id=1649334 about the use case in Openstack networking-ovn with octavia.
