Title:
Routing updates lost when multiple IPs attached to router
Status in neutron:
Expired
Bug description:
When attempting to run dual stacked networking at the gate
(https://review.openstack.org/#/c/140128/), IPv4 networking breaks,
with Tempest scenarios reporting no route to host errors for the
floating IPs that tempest attempts to SSH into.
The following errors are reported in the l3 agent log:
