Open Stack

So I bring up octavia using devstack (stable/mitaka).   I created a loadbalander and a listener(not create member yet) and start to look at how things are connected to each other.  I can ssh to amphora vm and I do see a haproxy is up with front end point to my listener.  I tried to ping (from dhcp namespace) to the loadbalancer ip, and ping could not go through.  I am wondering how packet is supposed to reach this amphora vm.  I can see that the vm is launched on both network(lb_mgmt network and my vipnet), but I don't see any nic associated with my vipnet:

And it seemed that amphora created a port from the vipnet for its vrrp_ip, but now sure how it is used and how it is supposed to help packet to reach loadbalancer ip

It will be great if somebody can help on this, especially on network side.

Thanks
