15:10:37 <Swami> I spoke to Sridhar about this bug yesterday. Sridhar have identified a fix and will be pushing in shortly.

15:12:08 <openstack> Launchpad bug 1774463 in neutron "RFE: Add support for IPv6 on DVR Routers for the Fast-path exit " [Undecided,Confirmed]
15:12:36 <Swami> haleyb: I need the patch that you referred to for proceeding with this IPv6 work for the FIP Namespace. Can you point me to the patch.
15:13:31 <haleyb> Swami: sorry, i keep forgetting, will dig it up now
15:13:44 <Swami> haleyb: Thanks that would help
15:15:06 <Swami> Regarding the ARP issue. #link https://bugs.launchpad.net/neutron/+bug/1774459
15:15:06 <openstack> Launchpad bug 1774459 in neutron "Update permanent ARP entries for allowed_address_pair IPs in DVR Routers" [High,Confirmed]
15:15:57 <Swami> I read your comments about using the Keepalivestate similar to IPMonitor. I am still investigating if it is possible. I will update the Bug with my findings on this.
15:17:10 <haleyb> ok, thanks
15:17:42 <Swami> haleyb: I am seeing this patch for  Pike is failing the functional tests that passed in queens and master. https://review.openstack.org/#/c/577012/
15:18:15 <Swami> haleyb: Not sure what is wrong with this. Can you take a look and comment if anything is missing.
15:18:32 <haleyb> Swami: i'll take a look at the failure
15:18:50 <Swami> haleyb: Ok Thanks
15:19:01 <Swami> haleyb: That's all I had for bugs today.
15:19:06 <Swami> haleyb: back to you
15:19:25 <haleyb> Swami: https://review.openstack.org/#/c/143917/ was the review i was thinking of
15:19:30 <haleyb> for ipv6 dvr
15:19:41 <Swami> Thanks
15:20:14 <haleyb> there's a link there to another change, and maybe look at some of robert's other changes
15:21:24 <Swami> Ok, will do that would help
15:21:46 <haleyb> i don't see any other recent L3 bugs, any others people want to bring up?
15:22:59 <Swami> haleyb: If you are done with bugs, I have some questions, may be in the opendiscussion
15:24:14 <haleyb> #topic dvr-bridge
15:24:36 <haleyb> i'm not sure anyone is here regarding dvr-bridge ?
15:25:15 <haleyb> moving on
15:25:40 <haleyb> #topic Open discussion
15:26:00 <haleyb> Swami: you had a topic
15:26:20 <Swami> haleyb: I had a question about the recent change to remove the external-bridge configuration.
15:26:38 <haleyb> yes, it had been deprecated some time ago
15:27:03 <Swami> haleyb: If external-bridge is removed how the fip traffic will flow when the fg port is associated with the br-int.
15:27:13 <Swami> Do we need to create additional bridges or how?
15:27:41 <Swami> Is there any documentation or pointer on how to handle the external traffic.
15:29:33 <haleyb> Swami: that's a good question.  i know the dvr fip code does a plug() right into the bridge
15:30:16 <Swami> haleyb: yes,
15:31:03 <Swami> haleyb: we should be having a migration strategy for people who are using the external bridge in the compute for fip traffic.
15:32:26 <Swami> haleyb: if you find any pointer let me know. I will also look into it.
15:32:55 <Swami> haleyb: Also I had another question on the ml2/l2pop/ovs
15:33:02 <haleyb> Swami: sure
15:34:00 <Swami> If for some reason the ovs port 'ofport' that is getting created is either removed or replaced, what would be the indication to the l2pop driver to replace the fdb_add_tun and fdb_remove_tun entries
15:34:29 <Swami> haleyb: I did see that in the codebase it handles these conditions only when the IP change or host change, but nothing about the 'ofport' change.
15:35:12 <Swami> haleyb: I am debugging an issue right now where they have fdb_flow for a stale 'ofport' and it was not cleared automatically and it had to be manually cleared.
15:35:50 <haleyb> Swami: pointer to code?
15:37:56 <Swami> haleyb: Do you remember seeing or hearing about this scenario. #link https://github.com/openstack/neutron/blob/master/neutron/plugins/ml2/drivers/l2pop/rpc_manager/l2population_rpc.py#L257
15:39:49 <haleyb> no, i don't remember this scenario
15:40:45 <Swami> haleyb: ok, It is little difficult to debug the issue because the logs are in different files and for some of the rpc commands like fdb_add and fdb_remove the logs are not captured in the openvswitch agent.
15:41:05 <Swami> haleyb: ok that's all I had.
15:41:34 <Swami> haleyb: Are you planning to present any paper for the Berlin summit
15:42:16 <haleyb> Swami: i hadn't given it much thought yet, are you?
15:42:38 <Swami> haleyb: Yes I thinking about it.
15:42:52 <Swami> haleyb: I will let you know if I have a topic
15:43:33 <Swami> haleyb: I am going on a vacation from July 6th to August 6th. (India)
15:44:09 <haleyb> Swami: enjoy your vacation!
15:44:12 <Swami> haleyb: thanks
15:44:53 <Swami> haleyb: spending a week in Dubai
15:45:07 <Swami> haleyb: on my way to India.
15:45:17 <haleyb> formula 1 race? or just a stop :)
15:45:45 <Swami> haleyb: Just site seeing. I will be also going to Ferrari park.
15:46:53 <haleyb> nice, Ferraris :)
15:47:15 <Swami> haleyb: Yep
