<p class="MsoNormal">Can you do that same capture but on the interface of the machine running the container? if everything is working correctly you should see the multcast and udp packets with the vxlan payloads. If those are missing, specifically in your
case I’d really be looking for the multicast packet since they carry the flooded traffic including DHCP requests, then you need to look really hard at your IGMP setup.<o:p></o:p></p>

<span lang="EN-US">We are working off the OSA deployment for a new cloud system we are building and everything seems to be working apart from the tenant VXLAN network. We have tried various troubleshooting but the initial DHCP request, is not making it out
of the linux bridge on the compute node. We have checked all physical networking and switch setup and they appear to be fine.</span><o:p></o:p></p>
