Public bug reported:

Openstack version: Pike
Openvswitch version: 2.7

Let's say I have a OS project that has 2 routers. The routers are
configured for HA and reside on pair of network nodes. Via VRRP, each
network has 1 Active and 1 Passive router. Neutron creates a custom HA
network for each project specific that assigns a vxlan vni (in our
config) to that HA network that allows the routers to send VRRP messages
between each other.

If we delete just one of the routers from the project, the assigned vni
for that HA network (discovered via openstack network show) gets removed
from a HA network entirely.

After the network nodes restart, the broken config is loaded and the
routers cease to function per the HA network lacking a vni assignment.

This problem didn't start happening until we upgraded to Pike.

See attached for proposed fix.
