blanson[m]Hi, I have a question because a few days ago I mentioned that we were seeing unicast traffic in one of our VM that wasn't destined to this VM. We use OVS with openvswitch firewall driver, and upon investigation, I noticed we do not have explicitly_egress_direct se to true, which, if I understand the documentation and code correctly, is specifically here to fix this issue, at the cost of cpu usage ? 12:23
lajoskatonablanson[m]: there was also some fixes for this bug (at least what I remember): https://bugs.launchpad.net/neutron/+bug/2051351 , as I see the patches were backported, so with setting explicitly_egress_direct these can be interesting also to have in your setup12:32
ralonsohblanson[m], the advantages of using `explicitly_egress_direct` are that it eliminates the egress unicast flooding, that improves the performance. The disadvantages: incompatible with HA routes12:32
blanson[m]ralonsoh: oh... I missed this bit, I'll re-read to ensure I got it right. lajoskatona: I checked our neutron version and we should have this on the affected clusters, will check the older ones to see if we need to backport it even further on our own, thanks 12:35
blanson[m]ralonsoh: could you explain quickly what you meant by "incompatible with HA routes" ? I'm not sure I understand the why 12:40
ralonsohblanson[m], this flag installs a explicit output flow for each MAC. HA routers with multiple MACs won't work (VRRP, L3 HA)12:46
ralonsohClaude finished the report, let me paste you it here12:46
