Hi, Can some one please explain it a bit or redirect me to the document. So on neutron node we need external interface br-ex (public IP) and than each tenant's router also occupies a real IP when we attach it to external net. I am wondering what is the path instances traffic take to go out? I mean will it go via the public IP attached to the router or its via br-ex? Regards..
