Windows server 2012 R2 can be configured as a Gateway VM in a two or
four node cluster on Hyper-v Host. Gateway VM or router enhance Data
Center by providing them a secure router for public or private cloud.
Gateway VM cluster can provide routing functionality up to 200 tenants.
Each Gateway VM can provide routing functionality for up to 50 tenants.
Two different versions of the gateway router are available in Windows Server 2012 R2.
RRAS Multitenant Gateway – The RRAS Multitenant Gateway router can be used for multitenant or non-multitenant deployments, and is a full featured BGP router. To deploy an RRAS Multitenant Gateway router, you must use Windows PowerShell commands
RRAS Gateway configuration and options:
Multi-tenancy is the ability of a cloud infrastructure to support the virtual machine workloads of multiple tenants, but isolate them from each other, while all of the workloads run on the same infrastructure. The multiple workloads of an individual tenant can interconnect and be managed remotely, but these systems do not interconnect with the workloads of other tenants, nor can other tenants remotely manage them.
This feature allow service provider the functionality to virtually isolate different subnets, VLANs and network traffic which resides in same physical core or distribution switch. Hyper-v network virtualization is a Network Virtualization Generic Routing Encapsulation NVGRE which allows tenant to bring their own TCP/IP and name space in cloud environment.
Systems requirements:
1-NIC Teaming in Hyper-v Host- You can configure NIC teaming in
Hyper-v Host for two 10GB NICs. Windows Server 2012 R2 Gateway VM with
four vNIC that are connected to the Hyper-V Virtual Switch that is bound
to the NIC Team.

RRAS Gateway configuration and options:
- Configure the RRAS Multitenant Gateway for use with Hyper-V Network Virtualization
- Configure the RRAS Multitenant Gateway for use with VLANs
- Configure the RRAS Multitenant Gateway for Site-to-Site VPN Connections
- Configure the RRAS Multitenant Gateway to Perform Network Address Translation for Tenant Computers
- Configure the RRAS Multitenant Gateway for Dynamic Routing with BGP
