Description Brent Eagles 2015-11-09 20:57:44 UTC

+++ This bug was initially created as a clone of Bug #1271336 +++

We should be able to explicitly configure the OVS ARP Responder feature. To enable:

 1. Enable L2 population (see https://bugzilla.redhat.com/show_bug.cgi?id=1271335)

 2. set the following value in the OVS Agent configuration for all nodes running an OVS agent:

[agent]
arp_responder = True

Comment 2 Emilien Macchi 2015-12-01 17:31:08 UTC

A patch in TripleO Heat Templates needs to be pushed to enabled this parameter (false by default):

Comment 5 Mike Burns 2016-04-07 20:57:01 UTC

This bug did not make the OSP 8.0 release.  It is being deferred to OSP 10.

Comment 7 Stephen Gordon 2016-06-09 18:49:18 UTC

Bulk update to reflect scope of Red Hat OpenStack Platform 9 and Red Hat OpenStack Platform does not include this issue (No pm_ack+).

Comment 9 Assaf Muller 2017-01-12 13:43:06 UTC

@Brent, would you kindly take care of this? We'd like to see the ability to configure the ARP responder, however it should be off by default at this point. In parallel we'll contact the performance team to see the effect of this knob and make recommendations about the default value in a future release.

Comment 10 Assaf Muller 2017-09-07 22:03:45 UTC

I'm closing this bug, with a greater focus on OVN in a future OSP offering, allocating time and energy in low priority bugs that are specific to ML2/OVS doesn't make sense.
