use Beryllium-SR2, for one route,bgp maybe advertising not best one to peer

Bug Resolved Won't Do Ajay L dongfang chen Sat, 18 Jun 2016 06:33:46 +0000 Sun, 3 Mar 2019 11:49:47 +0000 Mon, 8 Aug 2016 16:39:42 +0000 Bugzilla Migration Bugzilla Migration BGP 0 3 <p>Hi Dongfang</p> <p>I am able to see the issue with Beryllium-SR2 release. I am proposing a fix for it</p> <p>However it does not happen on latest/master (Boron) snapshot. Can you please try it on your setup and confirm the same? You can get the latest distribution snapshots here: <a href="https://nexus.opendaylight.org/content/repositories/opendaylight.snapshot/org/opendaylight/integration/distribution-karaf/0.5.0-SNAPSHOT/" class="external-link" target="_blank" rel="nofollow noopener">https://nexus.opendaylight.org/content/repositories/opendaylight.snapshot/org/opendaylight/integration/distribution-karaf/0.5.0-SNAPSHOT/</a></p> <p>Thanks<br/> Ajay</p> <p>stable/beryllium: <a href="https://git.opendaylight.org/gerrit/#/c/41423/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/41423/</a></p> <p>Issue not seen in master. Add-path feature changes seem to have taken care of this issue in master</p> <p>After further discussion it was decided that sending withdraw to remove older route when best route changes is not the right way to go about it for performance reasons. New best route should be communicated as part of update message and this will require controller to wait till it receives all updates from peer before doing best path calculation and sending updates.
