Comment 4 for bug 1531013

Hi Kevin,

The issue exists across all nodes in the environment, and continues to be an issue even after rebooting a node. I have not yet come across another environment with similar behavior.

The duplicates appear to be limited to the flooding entries (00:00:00:00:00:00) only and we are unable to replicate manually. The counts fluctuate so much that any attempt to 'append' a duplicate flooding entry (same MAC, interface, and VTEP addr) would go undetected.

In my testing. I have attempted to 'append' duplicate flooding entries on a vxlan interface *not* managed by Neutron, and it resulted in no observable change. Meaning, either the existing entry was overwritten or the command was simply ignored. Seems like expected behavior. I don't really know the conditions that could cause the observed behavior in the bug here, and unfortunately can't point you in any direction for duplicating it just yet. I will continue to dig into it.
