Bundle based resync fails after the OVS restart in L2 network

Bug Medium Resolved Done Karthikeyan Krishnan Fathima Thasneem Wed, 13 Jun 2018 12:38:54 +0000 Wed, 22 Jan 2020 13:17:27 +0000 Wed, 22 Jan 2020 13:16:57 +0000 natservice 0 6 <p>chetan has indicated that this codepath is observed in the vlan provider network based external network access usecase, and not in the bgpvpn based external network acccess usecase</p> <p>Ref CSIT - <a href="https://logs.opendaylight.org/releng/vex-yul-odl-jenkins-1/netvirt-csit-1node-openstack-queens-upstream-stateful-oxygen/533/robot-plugin/log_full.html.gz" class="external-link" target="_blank" rel="nofollow noopener">https://logs.opendaylight.org/releng/vex-yul-odl-jenkins-1/netvirt-csit-1node-openstack-queens-upstream-stateful-oxygen/533/robot-plugin/log_full.html.gz</a></p> <p>As per analysis, when tempest is ran, an vpn-instance-vpn-id entry will be made for each of the external-subnets. The Nat ExternalSubnetVpnInstanceListener.add() gets triggered on this which makes installation of 21-&gt;SNATGroup(225005) on each Dpn where this VPN has the presence. </p> <p>On tempest clean-up, I see an stale entry vpn-instance-vpn-id for this external-subnet. As a result, ExternalSubnetVpnInstanceListener.remove() not triggered resulting in this stale flows.</p> <p>@Fathima,</p> <p>I have raised an WIP review to address these stale entries(21-&gt;snat-group with the corresponding entry missing). Such stale entries are currently not seen with be below CSIT.</p> <p><a href="https://git.opendaylight.org/gerrit/#/c/73061/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/73061/</a></p> <p><a href="https://logs.opendaylight.org/releng/vex-yul-odl-jenkins-1/netvirt-csit-1node-openstack-queens-gate-stateful-fluorine/629/robot-plugin/log_full.html.gz#s1-s9-t3-k14-k2-k1-k2-k38" class="external-link" target="_blank" rel="nofollow noopener">https://logs.opendaylight.org/releng/vex-yul-odl-jenkins-1/netvirt-csit-1node-openstack-queens-gate-stateful-fluorine/629/robot-plugin/log_full.html.gz#s1-s9-t3-k14-k2-k1-k2-k38</a></p> <p>Will it be possible to validate the Bundle based resync UC with this patch-set??</p> <p> </p> <p>Hi Chetan,</p> <p>I gave a suite run picking your gerrit patch and observed the issue.</p> <p><a href="https://jenkins.opendaylight.org/sandbox/job/fathimanetvirt-csit-1node-openstack-pike-upstream-stateful-fluorine/1/" class="external-link" target="_blank" rel="nofollow noopener">https://jenkins.opendaylight.org/sandbox/job/fathimanetvirt-csit-1node-openstack-pike-upstream-stateful-fluorine/1/</a></p> <p>Thanks,</p> <p>A.Fathima Thasneem</p> <p>Hi Fathima, </p> <p>As discussed, I don't see the patch changes are taken with this CSIT run.
