no service running at port 9697

Here is my problem

$ sudo ip netns exec qrouter-429424ce-6d82-49cc-bc6a-9dc5236ba313 iptables-save | grep 169
-A neutron-l3-agent-PREROUTING -d 169.254.169.254/32 -p tcp -m tcp --dport 80 -j REDIRECT --to-ports 9697
$ sudo ip netns exec qrouter-429424ce-6d82-49cc-bc6a-9dc5236ba313 netstat -pantu | grep 9697

So somehow i don't see any service running at port 9697 when i check the namespace. I am using juno, wtih neutron + gre settings.

$ ps -efl | grep neutron

I had doubled chcked the l3_agent.ini, nova.conf and neutron.conf settings at the controller. But couldn't solve the issue. I don't see any errors at the logs also.

Any idea?
