<p class="MsoNormal">We will continue to troubleshoot further on this, and try to isolate why this is happening. It is the only ring we are having this issue with Kea on, multiple other instances on other rings are functioning just fine.<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We have a lingering issue that we are trying to work through and seem to be at a standstill each time we try and resolve our issue.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The issue is solely with VLAN’s that have more than 1 subnet.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We have tried adding into “Shared Networks” which solves the issue with one single VLAN, the issue is we have multiple VLAN’s that use more than one subnet. When adding an additional VLAN and subnet to the “shared network” category we
start getting IP issues with handouts and trying to handout from subnets that are not part of that node. I have tried using the relay function as well and have not managed to find a work around.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">All of our other VLAN’s with a single subnet are functioning as intended
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Below is a snip of the configuration. With the other nodes commented out this performs as expected. But when I comment them back in we start seeing issues.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Should we scrap the shared networks and move them back to individual networks and just add the relay to each? Or am I missing something here?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Any help would be appreciated<o:p></o:p></p>
