Performance issue observed while associating router to VPN

Bug Medium Verified Done Karthikeyan Krishnan RajaRajan Manickam VPNV6 Wed, 28 Mar 2018 18:43:40 +0000 Fri, 24 Aug 2018 06:50:21 +0000 Tue, 24 Jul 2018 04:29:54 +0000 Oxygen Oxygen-SR3 Fluorine 0 4 0 minutes 1 week <p>Current Analysis</p> <p>-------------------------</p> <p>Updation of RD values for each fib entry happens one by one for each route-entry , which is not the case for dual-stack alone. This behaviour is observed for ipv4 single-stack also.</p> <p> Have attached the logs .</p> <p> </p> <p>Karthikeyan,</p> <p>Assigned this to you. Please analyze/assign accordingly.</p> <p>Thanks,</p> <p>Kiran</p> <p>Hi,</p> <p>Have analysed the VPN/FIB manager code and observed that when BGP-VPN is associated to neutron router, the process of doing VPN-Swap is causing the problem of delay. Also observed each VPN interface update is delaying 2 sec (Which is existing in the current implementation code). So the overall VPN performance of the updating FIB entries is depends on the number of VPN interfaces in used network topology.</p> <p>Removing 2 sec delay in VPN interface update is throwing new exceptions from FIB manager. We need to think whole design of the VPN/FIB manager module to address this performance issue as a better way.</p> <p> </p> <p>Thanks &amp; Regards,</p> <p>Karthikeyan.</p> <p>Please refer the below gerrit links for required fix got merged into fluorine release.</p> <p><a href="https://git.opendaylight.org/gerrit/#/c/74176/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/74176/</a></p> <p><a href="https://git.opendaylight.org/gerrit/#/c/74454/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/74454/</a></p> <p> </p> <p>Please refer the below gerrit links for required fix got merged into stable/oxygen SR3 release.</p> <p><a href="https://git.opendaylight.org/gerrit/#/c/74317/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/74317/</a></p> <p><a href="https://git.opendaylight.org/gerrit/#/c/74455/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/74455/</a></p> <p> </p> <p> </p> Development Priority Rank 0|i03cen:
