Hello openstack-discuss,
With the removal of the linuxbridge mechanism driver, has anyone successfully completed an in-place migrationfrom LinuxBridge to OVN? I did come across this https://www.jimmdenton.com/migrating-lxb-to-ovn/ and that looks good as a one-shoit while biting the bullet and taking a full outage. However, I was wondering if it was possible to run lxb and ovn side-by-side and cut them over, say one network at a time.
This particular deployment was stood up using openstack-ansible back in the rocky days (now running antelope) and it appears that openstack ansible's default was lxb up until Zed.
Any suggestions or recommendations on the best path forward?
Also, will the dynamic routing agent work with ovn?
Hi Ricardo, for the dynamic routing with OVN you can check the ovn-bgp-agent project [1] and see if it would fit your needs. Note that it does not use any API from the Neutron dynamic routing. Jakub [1] https://opendev.org/openstack/ovn-bgp-agent
