Thanks for your response, ben,
I found these error logs will occur with hw-offload=true, This error will
disappear when I disable hardware offload.
It seems there is a bug processing igmp packet when hardware offload enabled.
I'm not familiar with this code, Could you provide any clue how to deb
Hi,
Continue this thread with some updates.
I finally got 4096 networks and 256 router created, 16 networks connecting
to each router. All routers are set as external gateway.
On underlay, those 256 gateway addresses on the provider network are
reachable. Ping is steady.
I launched 10 VMs on on
In that case, I can use set-connection to set one row.
Thanks!

Hi Han,
Sounds good. I am looking forward to incremental-processing,
and will go from there.
BTW, it would be great if you could let me know how to set probe
interval for 3-node cluster, here or in another thread.
Thanks!

Hi,
Since I have 3 OVN DB nodes, should I add 3 rows in connection table
for the inactivity_probe? Or put 3 addresses into one row?
"set-connection" set one row only, and there is no "add-connection".
How should I add 3 rows into the table connection?
Thanks!

Hi Han,
Thanks for clarifications! It's crystal clear.
My concern, in general, is blocking. For onv-northd, or OVSDB client,
(I assume all OVSDB clients are using the same library for connection,
proble, etc.?) when handing current event, it won't be interrupted to
handle any incoming event, righ

Is there any difference to restore DB on existing cluster vs. fresh cluster,
in terms of performance?
If I don't have to restore on fresh cluster, which is recommended?
For now, since ovn-northd always recomputes the whole DB, I guess not much
difference?
With incremental-process, would restorin

Hi,
Here is how I restore OVN DB.
* Stop all ovn-nb-db, ovn-sb-db and ovn-northd services.
* Clean up all DB files.
* Start all DB services. Fresh ovn-nb-db and ovn-sb-db clusters are up and
running.
* Set DB election timer to 10s.
* Restore DB to ovn-nb-db by ovsdb-client.
* Start all ovn-north
Thanks Numan for looking into it!
Probe is for health check only, it's not supposed to trigger translation,
even with incremental implementation. Translation should be triggered only
when a ovn-northd becomes active.
