IPV6 address is retained after removing the subnet from router and rebooting the VM

Bug Medium Verified Done Pratibha Narasapur Pratibha Narasapur VPNV6 Thu, 31 May 2018 11:55:13 +0000 Thu, 21 Jun 2018 10:15:27 +0000 Thu, 21 Jun 2018 10:15:27 +0000 0 2 <p>Hi Pratibha,</p> <p>Can you please provide the below details to confirm whether issue is there at ODL Controller side.</p> <p>Provide before and after subnet removed from the router.</p> <ul> <li>table 45 flow entries</li> <li>karaf logs with enabled DEBUG for IPv6Service Module (log:set DEBUG org.opendaylight.netvirt.ipv6service)</li> <li>Share the exact time (Server time at the time of removal) for subnet removed from the router. So that i can verify the karaf logs whether after removed the subnet from the router still Unsolicited RA packet is reaching to VM or not.</li> <li>If possible please do packet capture(tcpdump) on the VM side (Tap/VHU port). So that i can conclude whether still VM is receiving URA packet.</li> </ul> <p> </p> <p>I have tested the same scenario with latest oxygen/fluorine and issue is not observed.</p> <p> </p> <p>2018-06-01T14:34:11,050 | DEBUG | Thread-90 | IfMgr | 368 - org.opendaylight.netvirt.ipv6service-impl - 0.7.0.SNAPSHOT | Transmitting RA UNSOLICITED_ADVERTISEMENT for node openflow:392318374877, port openflow:392318374877:3</p> <p>2018-06-01T14:35:11,152 | DEBUG | Thread-90 | IfMgr | 368 - org.opendaylight.netvirt.ipv6service-impl - 0.7.0.SNAPSHOT | Transmitting RA UNSOLICITED_ADVERTISEMENT for node openflow:392318374877, port openflow:392318374877:3</p> <p>2018-06-01T14:36:11,253 | DEBUG | Thread-90 | IfMgr | 368 - org.opendaylight.netvirt.ipv6service-impl - 0.7.0.SNAPSHOT | Transmitting RA UNSOLICITED_ADVERTISEMENT for node openflow:392318374877, port openflow:392318374877:3</p> <p>2018-06-01T14:37:11,355 | DEBUG | Thread-90 | IfMgr | 368 - org.opendaylight.netvirt.ipv6service-impl - 0.7.0.SNAPSHOT | Transmitting RA UNSOLICITED_ADVERTISEMENT for node openflow:392318374877, port openflow:392318374877:3</p> <p>2018-06-01T14:38:11,451 | DEBUG | Thread-90 | IfMgr | 368 - org.opendaylight.netvirt.ipv6service-impl - 0.7.0.SNAPSHOT | Transmitting RA UNSOLICITED_ADVERTISEMENT for node openflow:392318374877, port openflow:392318374877:3</p> <p> </p> <p>Removed IPv6 subnet from the router.</p> <p>After that i have not seen any periodic unsolicited RA packet is sending from the ODL controller.</p> <p> </p> <p>As confirmed by bug-submitter issue is not reproducible with latest oxygen build.
