&lt;p&gt; 1. Ovsdb (Master, built from source)&lt;br/&gt;
    karaf is up (ports: 6640,6633,6653 and the neutron ports)&lt;/p&gt;

&lt;p&gt; 2. openstack control node is up, br-int and br-ex created with the public ineterface&lt;/p&gt;

&lt;p&gt; 3. openstack compute node&lt;/p&gt;

&lt;p&gt; 4. Created router + networks (reference: &lt;a href=&quot;http://www.flaviof.com/blog/work/how-to-odl-with-openstack-part3.html&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;http://www.flaviof.com/blog/work/how-to-odl-with-openstack-part3.html&lt;/a&gt;)&lt;/p&gt;

&lt;p&gt; 5. Created instances&lt;/p&gt;

&lt;p&gt; 6. Instances able to ping each other and also outside network to the L3 Gateway&lt;/p&gt;

&lt;p&gt; 7. Able to reach the instacnes from the l3 gateway and able to ssh &lt;/p&gt;

&lt;p&gt; 8. Restart ODL&lt;/p&gt;

&lt;p&gt; 9. Created new instances&lt;/p&gt;

&lt;p&gt;10. The instacnes are able to ping the other instances from the internal network. &lt;/p&gt;

&lt;p&gt;11. the new instances are not able to use the router and reach the external networks, also not reachable from the l3 gateway.&lt;/p&gt;</comment>

We don&apos;t really persist all the gateway ip that need to be resolved for the MAC, so when we restart the controller we loose those caches. This is my first guess, i need to investigate more.&lt;/p&gt;</comment>
                            <comment id="41005" author="jose.alcaraz-calero@uws.ac.uk" created="Wed, 3 Feb 2016 07:14:58 +0000"  >&lt;p&gt;Hi Anil, Hi Venkatrangan, &lt;/p&gt;

&lt;p&gt;Please, let me extend the description of this bug. If you have a clean neutron + clean ODL with &quot;odl-ovsdb-sfc&quot; feature and you create networks, subnetworks and instances using GRE/VXLAN. They will be able to ping, to enforce security groups, multi-tenancy isolation, etc. However, if you &quot;reboot&quot; the infrastructure (soft shutdown with proper shuting down of all services). Then, you will see how the &quot;neutron gateway&quot; cannot react anymore any instances. In fact, you will not receive any IP address via DHCP, etc from the gateway.  &lt;/p&gt;

&lt;p&gt;It means that the problem is not related to the &quot;creation of instances&quot;. It seems that there is a mismatch sync between the namespaces, tunnels and ODL controller. This bug is weird because jenkins can pass it even if the bug still there. &lt;/p&gt;

&lt;p&gt;I have been working in the bug for hours so happy to provide any information you may required. i can reproduce it many times. &lt;/p&gt;

&lt;p&gt;Using: liberty multi-node over trusty with GRE/VXLAN tunnels + ovs 2.3.2 + ODL 0.4.0-SNAPSHOP (generated 4 days ago). &lt;/p&gt;

&lt;p&gt;No errors reported in OVS, Neutron-DHCP, Nova-Controller, Neutron-Server, ODL and Nova-Compute. &lt;/p&gt;

&lt;p&gt;I know that I&apos;m using &quot;odl-ovsdb-sfc&quot;. However, notice that I said clean ODL so that no any SFC rules have been even defined. It seams that it is a problem related to OVSDB. &lt;/p&gt;

&lt;p&gt;Thanks in advance, &lt;br/&gt;
Jose&lt;/p&gt;</comment>
