<div dir="ltr"><div><div><div><div>I am reading through the blueprint created by Randy to bind dnsmasq into qrouter- namespace:<br><br><a href="https://blueprints.launchpad.net/neutron/+spec/dnsmasq-bind-into-qrouter-namespace">https://blueprints.launchpad.net/neutron/+spec/dnsmasq-bind-into-qrouter-namespace</a><br>
<br></div>I don't think I can follow the reason that we need to change the namespace which contains dnsmasq process and the device it listens to from qdhcp- to qrouter-. Why the original namespace design conflicts with the Router Advertisement sending from dnsmasq for SLAAC?<br>
<br></div>From the attached POC result link, the reason is stated as:<br><br>"Even if the dnsmasq process could send Router Advertisement, the default gateway would bind to its own link-local address in the qdhcp- namespace. As a result, traffic leaving tenant network will be drawn to DHCP interface, instead of gateway port on router. That is not desirable! "<br>
<br></div>Can Randy or Shixiong explain this more? Thanks!<br><br></div>Xuhan <br></div>
