14:00:23 <openstack> The meeting name has been set to 'neutron_l3'
14:01:01 <haleyb> hi, and just an fyi that i'm in a conflicting meeting but will notice a ping with my nick
14:01:12 <liuyulong> sure
14:01:28 <liuyulong> Today we will be a short meeting.
14:01:53 <liuyulong> I have no announcements and only one L3 bug.
14:03:11 <liuyulong> OK, let's directly starts the Bugs topic.

14:04:14 <liuyulong> First one
14:04:15 <liuyulong> #link https://bugs.launchpad.net/neutron/+bug/1889388
14:04:16 <openstack> Launchpad bug 1889388 in neutron "[OVN] access between Floatings ip and instance with Direct External IP" [Undecided,New]
14:05:35 <liuyulong> It is taged as OVN backend, but I have never try to run instance in such case for OVS backend.
14:06:51 <liuyulong> It's a corner case, I will check it in our OVS deployment.
14:07:11 <slaweq> liuyulong: hi
14:07:24 <slaweq> I have some urgent d/s issue so I will just be lurking here
14:07:27 <haleyb> and i'm assuming there's a SG rule for access?  there was no answer to rodolfo's question either
14:07:43 <liuyulong> slaweq, hi
14:08:03 <liuyulong> slaweq, sure, go ahead, : )
14:09:00 <liuyulong> haleyb, IMO whether in the same host should not be the problem, the instance can be created in different hosts.
14:10:08 <liuyulong> For OVN, I guess the data pipeline may lack of some metadata/tag/header for packets between this two VMs.
14:10:19 <haleyb> well, sometimes there are specific issues when both are on the same host, hairpin issue for example
14:11:30 <liuyulong> For OVS, this may do not work either since there are also some block flows in the physical bridges.
14:12:02 <haleyb> right, someone would have to reproduce it
14:13:36 <liuyulong> Besides, amotoki asked one question about the tag "l3-dvr-backlog".
14:13:54 <liuyulong> Quote
14:14:00 <liuyulong> "l3-dvr-backlog tag was originally introduced to identify DVR feature
14:14:01 <liuyulong> gaps. What should we use for OVN L3 feature gaps?"
14:14:31 <haleyb> i think we have just an 'ovn' tag
14:15:00 <haleyb> we could add a new one for the gaps
14:15:15 <liuyulong> I don't know the tag history, but IMO, a one shot tag may same filter works.
14:15:25 <liuyulong> s/same/save
14:16:09 <haleyb> i know we added the ovn one when we merged the code
14:17:26 <liuyulong> OK, thank you for the information.
14:17:29 <liuyulong> Next
14:17:32 <liuyulong> #link https://bugs.launchpad.net/neutron/+bug/1890400
14:17:33 <openstack> Launchpad bug 1890400 in neutron "Default gateway in HA router namespace not set if using Keepalived 1.x" [High,In progress] - Assigned to Slawek Kaplonski (slaweq)
14:17:54 <liuyulong> slaweq has uploded the fix: https://review.opendev.org/#/c/745641/
14:18:23 <liuyulong> A simple config option, it's fine to me.
14:19:42 <liuyulong> Users should be informed by the release note.
14:20:24 <haleyb> yes, it's not perfect, but we have no way of specifying a keepalived version afaik
14:20:55 <liuyulong> yes, that's the main point.
14:21:14 <liuyulong> Alright, no more L3 bugs from me now.
14:21:59 <liuyulong> Let's continue to discuss something in next section.
14:22:11 <liuyulong> #topic On demand agenda
14:22:39 <liuyulong> #link https://review.opendev.org/#/c/601336/
14:22:53 <liuyulong> I noticed that slaweq uploaded a new patch set for this one.
14:24:57 <liuyulong> But no update for the comments of patch set 42, if this will be carried on again, we should fix those.
14:25:23 <liuyulong> Next should be this:
14:25:29 <liuyulong> Floating IP's for routed networks
14:25:38 <liuyulong> #link https://review.opendev.org/#/c/486450/
14:25:59 <liuyulong> #link https://review.opendev.org/#/c/669395/
14:26:33 <slaweq> liuyulong: yes, for now I only repaced it and resolved conflicts
14:26:35 <slaweq> nothing else
14:27:06 <liuyulong> slaweq, cool
14:27:41 <liuyulong> For this routed network stuffs, it is perrty good now, we can move forward IMO.
14:29:32 <liuyulong> OK, no more things from me now.
14:30:13 <liuyulong> I will hold this section a few minutes open, feel free to start your topic.
14:32:51 <haleyb> nothing else from me
14:36:14 <slaweq> nothing from me neighter
