Public bug reported:

We all know the current implementation of L3 router HA based on
Ml2/OVN[1][2], but I haven't found the process for conntrack state
synchronization during gateway failover/failback.

Does OVN currently not support state synchronization for DVR's external
gateway? If so, do we have any plans for this?
