We made in our TestLAB ICTCUMULUS (Means CLOUDS) a NVGRE (Network Virtualization using Generic Routing Encapsulation) Gateway with System Center 2012 R2 Virtual Machine Manager.
Before you make the Microsoft NVGRE Gateway see these blogposts here :
The Microsoft Windows Server Gateway is active.
Now we create VM Network with isolation called Tenant Blue.
We create an IP Pool for the Blue Tenant network.
We now create a Hyper-V Port Profile for the VM’s in Tenant Blue
Now we deploy a Virtual Machine
We Create a Virtual Machine in the isolated Blue Tenant.
VM is automatically configured with an IP-adress from the IP-Pool (192.168.99.2):
VM communicates via the NVGRE (via NAT) with the internet:
Our virtualization gateway host is using a Provider Address (192.168.98.2) used for network virtualization:
We created two more VM in the blue tenant to see some more results in the next step:
We can see our three created VMs with Customer address mapped to Provider Address if we run the powershell command Get-NetVirtualizationLookupRecord on the gateway host (ras01):
