Description Alex Stupnikov 2023-07-31 09:11:54 UTC
Description of problem:

The following messages are logged by OVN DB sync tool for subset of routers:

2023-07-05 10:17:54.423 174237 WARNING networking_ovn.ovn_db_sync [req-f2b32c20-7faa-437c-b4aa-b503f21c4eae - - - - -] Router UUID static routes [{'destination': '::/0', 'nexthop': 'IPV6_ADDR'}] found in OVN but not in Neutron

I am struggling to understand why these messages are logged after taking a look at neutron_ovs DB contents and OVN Northd DB: it looks like we are talking about standard default route for external router's GW. I either miss something or there is a disparity in different place and reported message is red herring.


Version-Release number of selected component (if applicable):
RHOSP 16.2.

How reproducible:
Customer executed neutron-ovn-db-sync-util with --ovn-neutron_sync_mode=log argument
