configured by Neutron and set on interfaces matching the bridge mappings. At
least, it works that way in Devstack.
Outbound SNAT
-------------
Outbound connectivity (that traverses the Neutron/OVN router) is known to be problematic
due to a bug in the way External port priority is handled differently than port assignment
than the Chassis Gateway, the very same mentioned previously. Ultimately this can create
a mismatch between the ports and results in intermittent traffic loss. A known workaround
is to manually update the HA Chassis Group and Gateway Chassis priorities so these are in sync
for a given Neutron network and associated router.
This is being tracked as `bug 1995078 <https://bugs.launchpad.net/neutron/+bug/1995078>`_.
