Title:
  Arista ML2 Driver enhancements to improve the Sync performance  for
  scale deployments

Status in OpenStack Neutron (virtual network service):
  Fix Released

Bug description:
  When either end of the Arista ML2 driver reloads (Opestack controller
  running Neutron or Arista EOS), a full sync of DB state between the
  Neutron DB and EOS State is required to ensure that all tenant
  networks and ports are appropriately configured on the Arista
  Hardware.

  For large deployments (e.g thousands of networks and thousands of
  VMs), re-syncing the state, and hence rebuilding the configuration,
  could take a very long time. We need to introduce a bulk-sync
  mechanism so that such large syncs could be accomplished in seconds as
  opposed to minutes.
