As I know,  now dragonflow still use neutron l3-agent for snat, so the l3-agent is enabled and router namespace  be created.

Hi 


The reason why a namepspace be created while creating router is just because l3-agent is enabled. You can disable it as you want to.


At present, there is only dhcp app in dragonflow need packets from datapath, so you will observe controller related flows after you create vms in subnet where dhcp is enabled. 


BTW, if you want the all flows showed in br-int, including hidden flows, you can use command “ovs-appctl bridge/dump-flows br-int”

Hi ,everybody:

when I deploy DragonFlow, I start neutron-server ,df-local-controller and df-l3-router, but there still are router namespace when I create routers ,I check ovs flow table ,there is no CONTROLLER actions for ip traffic ,so I guess something wrong with my conf.
below are my neutron.conf and l3_agent.ini respectively

Could anyone check with this problem for me ?
