all VpnPortIpToPort entries (including configuration ones) are lost from ODL cache after reboot

I believe that the following flow will result in missing table=19 rule for the router interface:<br/> 1. Configure a router which exists on DPN X<br/> 2. ODL reboot (VpnPortIpToPort cache is cleared)<br/> 3. Add a VM which is connected to the router, but on a new DPN</p> <p>The remaining issue hanging this bug is being addressed here:<br/> <a href="https://git.opendaylight.org/gerrit/#/c/47965/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/47965/</a></p> Duplicate NETVIRT-273 Development External issue ID 7142 External issue URL Rank 0|i01qpr:
