Comment 4 for bug 2024385

This is an intriguing approach. If the no backwards compatibility issue is too big to swallow for NGS an alternative would be to implement this in ML2 networking-baremetal which have an agent with HA support already. NOTE: the HA implementation used there might not be fit for this usecase. The switch configuration support in networking-baremetal is quite recent, _experimental_ and afik not used by anyone in production i.e I would consider breaking backward compatibility a non-issue.
