While learning the basics of vCloud networking, I came across this blog post which says (in respect to the port group which is backing the external network):
Of course it is heavily recommended to set this portgroup up with a VLAN for layer 2 isolation, again note that this is an outbound facing connection for your Org or for multiple Orgs.
and
As said, an external network can be shared between organizations but is typically created per organization and is your connection from or to your virtual datacenter.
My question is: if we create multiple external networks (one for every organization), should they all be backed by the same port group, or different port groups ? I realize there may not be one right answer, but will appreciate any help on, what is the recommended way and why ?
