Configuring the BIG-IP System as an HNV Gateway

Overview: Using the BIG-IP system as a Hyper-V Network Virtualization gateway

You can set up the BIG-IP® system to be an NVGRE gateway from a Microsoft Hyper-V virtualized network to external networks, and to provide services within the virtualized network. Each Hyper-V Network Virtualization (HNV) routing domain requires a number of per-subnet (VSID) NVGRE tunnels. For each HNV routing domain, you need to create a single, inbound-only tunnel with special inbound packet processing. Inbound NVGRE tunnels process traffic that was forwarded by HNV distributed routers, which use a special VSID to forward all routed packets to a gateway. Packets received from the inbound tunnel are internally remapped to the correct per-subnet tunnel. Thus, all decapsulated packets appear to be arriving only from the correct per-subnet tunnel.

Creating per-subnet tunnels for Hyper-V Network Virtualization routing domains.

You can configure an NVGRE inbound-only tunnel when you are using the BIG-IP system as a gateway between Microsoft Hyper-V Network Virtualization networks and external networks.
  1. On the Main tab, click
    Network
    Tunnels
    Tunnel List
    Create
    or
    Carrier Grade NAT
    Tunnels
    Create
    .
    The New Tunnel screen opens.
  2. In the
    Name
    field, type a unique name for the tunnel.
  3. From the
    Profile
    list, select
    nvgre
    .
    This setting tells the system which tunnel profile to use. The system-supplied NVGRE profile is adequate. To change the settings, you can create a new NVGRE profile, which then appears in this list.
  4. In the
    Key
    field, type the special Virtual Subnet Identifier (VSID) that is used by Hyper-V Network Virtualization distributed routers to forward all routed packets to a gateway.
    This field appears above the
    Profile
    field when you select a profile that requires this setting.
  5. In the
    Local Address
    field, type the local endpoint IP address.
    This should be a floating self IP address.
  6. In the
    Secondary Address
    field, select
    Specify
    , and type the non-floating local IP address of the tunnel.
  7. For the
    Remote Address
    list, retain the default selection,
    Any
    .
  8. From the
    Mode
    list, select
    Inbound
    .
  9. From the
    Traffic Group
    list, select the traffic group that includes the local IP address for the tunnel.
  10. Click
    Finished
    .
If you are using the BIG-IP system as a gateway, the preferred method is to install the F5 Networks HNV Gateway PowerShell Module in the System Center Virtual Machine Manager (SCVMM) for integration into a Microsoft Hyper-V environment.
