I believe this issue was addressed in
https://review.opendev.org/c/openstack/neutron/+/864051.

However, there are some other considerations around distributed floating
IPs with OVN and the extra router attributes in the context of OVN
routers relevant to NDR: https://bugs.launchpad.net/neutron/+bug/2022058

Title:
  Neutron-dynamic-routing does not work with OVN

Status in OpenStack Neutron Dynamic Routing charm:
  New
Status in Ubuntu Cloud Archive:
  New
Status in neutron:
  Confirmed

Bug description:
  When using OVN as Neutron backend, announcing prefixes with neutron-
  dynamic-routing is currently not working due to changes in the
  database structure. Some attempt to fix this has been made in
  https://review.opendev.org/c/openstack/neutron-dynamic-
  routing/+/814055 but wasn't successful.

  This is a major stop gap for production deployments which are using
  BGP to provide connectivity for IPv6 subnets in tenant networks.
