Bug Resolved Done Hari Krishna Jamo Luhrsen Wed, 8 Mar 2017 18:12:47 +0000 Tue, 4 Apr 2017 03:11:47 +0000 Tue, 4 Apr 2017 03:11:47 +0000 Carbon General 0 4 <p>In TC , "Ping Vm Instance1 In network_2 From network_1" , 60.0.0.3 is pinged from 50.0.0.2 . Both 50.0.0.0/24 and 60.0.0.0/24 subnets are added to router. <br/> There are three DPNs i.e OS_CONTROL_NODE , OS_COMPUTE_1 , OS_COMPUTE_2 .</p> <p>Routes 50.0.0.2 and 60.0.0.2 are on OS_CONTROL_NODE.<br/> Routes 50.0.0.4 and 60.0.0.4 are on OS_COMPUTE_1.<br/> Routes 50.0.0.3,50.0.0.5 and 60.0.0.3,60.0.0.5 are on OS_COMPUTE_2.</p> <p>All the above routes need to be on all 3 DPNs , as they belong to same router (RouterVPN). </p> <p>OS_CONTROL_NODE, OS_COMPUTE_1 has all 8 routes , but OS_COMPUTE_2 has only 7 routes. The missing route on OS_COMPUTE_2 is 50.0.0.2 . Hence ping response can't go out of OS_COMPUTE_2.</p> <p>When config/opendaylight-inventory:nodes is checked , OF rule for 50.0.0.2 is present on only 2 DPNs (as shown below).</p> <p>{"id":"L3.128304936239059.21.b3f3ac31-20ac-4b8c-b8a9-b020f77c76d6.42.50.0.0.2","priority":42,"table_id":21,...</p> <p>{"id":"L3.172218481588998.21.b3f3ac31-20ac-4b8c-b8a9-b020f77c76d6.42.50.0.0.2","priority":42,"table_id":21 ...</p> <p>Will further investigate logs to see why 50.0.02 is not programmed on OS_COMPUTE_2</p> <p><a href="https://git.opendaylight.org/gerrit/53355" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/53355</a></p> <p><a href="https://git.opendaylight.org/gerrit/53355" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/53355</a></p> <p>The following fixes address this bug:</p> <p><a href="https://git.opendaylight.org/gerrit/53807" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/53807</a></p> <p><a href="https://git.opendaylight.org/gerrit/53355" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/53355</a></p> <p><a href="https://git.opendaylight.org/gerrit/53628" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/53628</a></p> <p>Hence I am moving this bug to RESOLVED state.</p> <p>Jamo, </p> <p>If you see this problem reappearing in upstream Carbon jobs, please re-open this bug with appropriate log links.</p> <p>Vivek</p> Development External issue ID 7938 External issue URL Rank 0|i01sav: Status Whiteboard csit:sporadic_failures
