Sridhar have identified a fix and will be pushing in shortly. 15:10:51 So I think we are good on this for now. 15:11:08 great 15:11:19 I should thank Miguel for following up with this. 15:12:08 #link https://bugs.launchpad.net/neutron/+bug/1774463 15:12:08 Launchpad bug 1774463 in neutron "RFE: Add support for IPv6 on DVR Routers for the Fast-path exit " [Undecided,Confirmed] 15:12:36 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 Swami: sorry, i keep forgetting, will dig it up now 15:13:44 haleyb: Thanks that would help 15:15:06 Regarding the ARP issue. #link https://bugs.launchpad.net/neutron/+bug/1774459 15:15:06 Launchpad bug 1774459 in neutron "Update permanent ARP entries for allowed_address_pair IPs in DVR Routers" [High,Confirmed] 15:15:57 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 ok, thanks 15:17:42 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 haleyb: Not sure what is wrong with this. Can you take a look and comment if anything is missing. 15:18:32 Swami: i'll take a look at the failure 15:18:50 haleyb: Ok Thanks 15:19:01 haleyb: That's all I had for bugs today. 15:19:06 haleyb: back to you 15:19:25 Swami: https://review.openstack.org/#/c/143917/ was the review i was thinking of 15:19:30 for ipv6 dvr 15:19:41 Thanks 15:20:14 there's a link there to another change, and maybe look at some of robert's other changes 15:21:24 Ok, will do that would help 15:21:46 i don't see any other recent L3 bugs, any others people want to bring up? 15:22:59 haleyb: If you are done with bugs, I have some questions, may be in the opendiscussion 15:24:14 #topic dvr-bridge 15:24:36 i'm not sure anyone is here regarding dvr-bridge ? 15:25:15 moving on 15:25:40 #topic Open discussion 15:26:00 Swami: you had a topic 15:26:20 haleyb: I had a question about the recent change to remove the external-bridge configuration. 15:26:38 yes, it had been deprecated some time ago 15:27:03 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 Do we need to create additional bridges or how? 15:27:41 Is there any documentation or pointer on how to handle the external traffic. 15:29:33 Swami: that's a good question. i know the dvr fip code does a plug() right into the bridge 15:30:16 haleyb: yes, 15:31:03 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 haleyb: if you find any pointer let me know. I will also look into it. 15:32:55 haleyb: Also I had another question on the ml2/l2pop/ovs 15:33:02 Swami: sure 15:34:00 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 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 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 Swami: pointer to code? 15:37:56 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 no, i don't remember this scenario 15:40:45 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 haleyb: ok that's all I had. 15:41:34 haleyb: Are you planning to present any paper for the Berlin summit 15:42:16 Swami: i hadn't given it much thought yet, are you? 15:42:38 haleyb: Yes I thinking about it. 15:42:52 haleyb: I will let you know if I have a topic 15:43:33 haleyb: I am going on a vacation from July 6th to August 6th. (India) 15:44:09 Swami: enjoy your vacation! 15:44:12 haleyb: thanks 15:44:53 haleyb: spending a week in Dubai 15:45:07 haleyb: on my way to India. 15:45:17 formula 1 race? or just a stop :) 15:45:45 haleyb: Just site seeing.
