Description Aviv Guetta 2017-03-28 10:00:22 UTC

This bugzilla is opened in order to make sure we include OVS-2.5 patch [1] in RHOS 10.
Description (patch):

When iterating the list of mrouters, skip any that are not on the same
vlan as the multicast packet to be forwarded. This bug was causing
duplicate packets when more than one mrouter was behind a trunk port.

Comment 2 Flavio Leitner 2017-03-29 00:50:12 UTC

Hi,

The patch mentioned in the comment#0 is available as part of bz#1335865 for the fast datapath beta which is now being pushed to production due to bz#1426237 (openvswitch-2.6.1-10.git20161206.el7fdp).

The goal is to provide it as update to OSP10z if possible, so feel free to test and validate the package in the meantime.  Just note that for DPDK users upgrading from OVS 2.5 to OVS 2.6 requires additional OSP support/changes. If that's the case here, let's us know before start any test or upgrade the OVS package.

Thanks!

Hi Flavio,
We use the beta you mentioned (openvswitch-2.6.1-10.git20161206.el7fdp), currently I didn't receive any specific comments from consulting.
I prefer to leave this bug open for tracking until this feature will be officially inserted to OSP 10.

Aviv
