Dear Sir:

 

I try to create an internal network by:

$ openstack network create --internal int-net-1

 

When you show the network in detail, it is show “router:external=Internal”.

But still hook up to the provider’s network. It will auto assign the provider network & assign a VLAN.

$ openstack network show int-net-1
