I am reading through the blueprint created by Randy to bind dnsmasq into qrouter- namespace: https://blueprints.launchpad.net/neutron/+spec/dnsmasq-bind-into-qrouter-namespace 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? >From the attached POC result link, the reason is stated as: "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! " Can Randy or Shixiong explain this more? Thanks!
