The computes which don't host the VM send the packet over the tunnel, and therefore cause duplicate packets to arrive to the VM.</p> <p>Operating System: All<br/> Platform: All</p> NETVIRT-167

floating IP rules in table=21 are created in all computes - creating duplicate packets

Bug Resolved Done Unassigned Koby Aizer Wed, 21 Sep 2016 19:38:12 +0000 Thu, 19 Oct 2017 21:27:57 +0000 Thu, 13 Oct 2016 09:45:06 +0000 Boron General 0 0 <p>Vivekanandan Narasimhan's review:<br/> <a href="https://git.opendaylight.org/gerrit/#/c/46096/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/46096/</a></p> <p>Closing this bug as fixed. The eventual fix was removing the floating IP dstmac rules from table=19 (see the change in the comment above). This seems to be the proper solution for the duplicate packets, as the table=21 rules are required for hairpinning.</p> Development External issue ID 6780 External issue URL Rank 0|i01q4n:
