Usually CI nodes should always have an IPv4 address and default route, but sometimes this seems to be broken.
I proposed a workaround in devstack to only query this when needed for linuxbridge-agent https://review.opendev.org/760325, maybe one can also extend the code to check for an IPv6 default route when no v4 route is found.
