Thanks Kevin. I added it to get_router_ids [1], which is called when full_sync flag is set(i.e when agent is AGENT_REVIVED, updated or started) and not in get_routers/sync_routers. [1] https://review.openstack.org/#/c/470905/ On Sat, May 27, 2017 at 2:54 AM, Kevin Benton wrote: > I recommend a

I recommend a completely new RPC endpoint to trigger this behavior that the L3 agent calls before sync routers. Don't try to add it to sync routers which is already quite complex. :) On Fri, May 26, 2017 at 7:53 AM, Anil Venkata wrote: > Thanks Kevin, Agree with you. I will try to implement this

Just triggering a status change should just be handled as a port update on the agent side which shouldn't interrupt any existing flows. So an l3 agent reboot should be safe in this case. On May 26, 2017 6:06 AM, "Anil Venkata" wrote: > On Fri, May 26, 2017 at 6:14 PM, Kevin Benton wrote: > >> P

Perhaps when the L3 agent starts up we can have it explicitly set the port status to DOWN for all of the HA ports on that node. Then we are guaranteed that when they go to ACTIVE it will be because the L2 agent has wired the ports. On Fri, May 26, 2017 at 5:27 AM, Anil Venkata wrote: > This is r

This is regarding https://bugs.launchpad.net/neutron/+bug/1597461 Earlier to fix this, we added code [1] to spawn keepalived only when HA network port status is active. But, on reboot, node will get HA network port's status as ACTIVE from server(please see comment [2]), though l2 agent might not h
