If that ping is failing, then is something<br/> in the network adding even more encaps? I know the math says it should only<br/> add up to 1494 which is less than our 1500 on the nics. Is there something<br/> we are forgetting?</p> <p>BUT, I changed the job to use 1200 for the network mtu and it's passing. </p> <p><a href="https://logs.opendaylight.org/sandbox/jenkins091/netvirt-csit-1node-openstack-mitaka-jamo-upstream-stateful-carbon/11/archives/log.html.gz#s1-s2-s1-k1-k4-k5" class="external-link" target="_blank" rel="nofollow noopener">https://logs.opendaylight.org/sandbox/jenkins091/netvirt-csit-1node-openstack-mitaka-jamo-upstream-stateful-carbon/11/archives/log.html.gz#s1-s2-s1-k1-k4-k5</a></p> Development External issue ID 8033 External issue URL Rank 0|i01sj3:
