This change should look in both\nthe ipv4 and ipv6 route table.  A similar check in the L3 setup code\nis also updated.\n\n[1] https://review.opendev.org/#/c/739139/\n[2] https://d4eb7e3efe98cba79a4b-f4d168cdb20f40841821e4b213645c0f.ssl.cf2.rackcdn.com/739139/12/gate/neutron-tempest-plugin-scenario-linuxbridge/9a6b4f7/controller/logs/worlddump-latest.txt\n[3] https://opendev.org/openstack/devstack/src/branch/master/lib/neutron-legacy#L236\n\nCloses-Bug: #1902002\nChange-Id: I839e8c222368df98fec308cf41248a9dd0a8c187\n",
