*** Bug 2014305 has been marked as a duplicate of this bug. *** @ralonsoh is there a 16.1 bug to track this work? Verizon will require this fix for 16.1.8. Hello Karrar: I've created [1]. Once we have the 16.2 code tested and verified, I'll backport this RFE to 16.1. Regards. [1]https://bugzilla.redhat.com/show_bug.cgi?id=2024692 According to our records, this should be resolved by openstack-neutron-15.3.5-2.20220113150031.el8ost. This build is available now. Successfully verified.
