Hello Parsa:

Please check [1]. This is how routed provider networks work in OpenStack neutron. In this topology you can have isolated L2 segments and a defined set of compute nodes per segment.However this architecture requires the L3 layer to be handled outside Neutron. This is something you should take into consideration.

Regards.

hello is there any way to assign a specific subnet in openstack to a specific compute ? For example subnets with ip 192.168.11.0/24 only can assign to instances on compute6 .
