Description Assaf Muller 2017-03-17 19:16:03 EDT

The Neutron and OVN databases should stay in sync even in the case of intermittent failures, missed and out of order notifications.

Comment 4 Assaf Muller 2017-04-24 09:31:25 EDT

Spec not yet posted, pushing to milestone 3.

Comment 10 Miguel Angel Ajo 2017-10-04 09:18:58 EDT

We need to sync with QE to prepare a testing plan for this, we could potentially reuse (as @nyechiel suggested) the ODL testing plans for this feature.

Miguel, If its same test cases as ODL it will be easy to reuse the ODL testing plans for this feature. can you review the ODL testing plans to make sure its relevant to OVN?

Comment 16 Lucas Alvares Gomes 2017-12-04 09:39:52 EST

Comment 23 Lucas Alvares Gomes 2018-04-30 09:22:56 EDT

Backporting the functional tests that are run upstream to exercise the maintenance task [0], this is needed so that we can verify this RFE.
