Hello,

Do what Thomas suggested or disable LLDP because it’s also possible that you are leaking information about your compute node to running instances.

Best regards

Hello, I am using ovn 21.09 with neutron 19.0. I am continuously seeing below lldpd errors in my journalctl and syslog of compute nodes. Is there anything to worry about?

I'd suggest adding this to your setup so you're not annoyed anymore:

# cat /etc/lldpd.d/only-eth.conf configure system interface pattern eth*

That's what OCI [1] does by default.
