    Create
    The New Tunnel screen opens.
  5. In the
    Name
    field, type a unique name for the tunnel.
  6. From the
    Profile
    list, select the type that corresponds to the encapsulation protocol you want to use.
    The selection
    ipip
    is the same as
    ip4ip4
    , but
    ipip
    is compatible with configurations from an earlier release.
  7. From the
    Profile
    list, select the tunnel profile you created for network virtualization.
    This selection must be a profile based on either the
    gre
    or
    vxlan
    parent profile, depending on your virtualized network environment.
  8. From the
    Profile
    list, select
    fec
    .
    This setting tells the system which tunnel profile to use. The system-supplied
    fec
    profile is configured for adaptive behavior for the number of source and repair packets. If you create a new FEC profile with custom settings, the profile then appears in this list, where you can select it.
  9. From the
    Profile
    list, select
    vxlan
    .
    This setting tells the system which tunnel profile to use. The system-supplied VXLAN profile specifies port
    4789
    . To change the port number, you can create a new VXLAN profile, which then appears in this list.
  10. From the
    Profile
    list, select
    vxlan-multipoint
    .
  11. From the
    Profile
    list, select
    vxlan-gpe
    .
    This setting tells the system which tunnel profile to use. The system-supplied
    vxlan-gpe
    profile specifies port
    4790
    . To change the port number, you can create a new VXLAN-GPE profile, which then appears in this list.
  12. 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.
  13. From the
    Profile
    list, select
    ipip
    or
    gre
    .
    The
    ipip
    selection can also be one of the IPIP variations:
    ip4ip4
    ,
    ip4ip6
    ,
    ip6ip4
    , or
    ip6ip6
    .
  14. From the
    Profile
    list, select
    dslite
    .

    Profile
    list, select
    IPsec
    .
  17. From the
    Profile
    list, select
    v6rd

    Local Address
    field, type the IP address of the BIG-IP system.
  21. In the
    Local Address
    field, type the IP address of the local endpoint.
    If you are using an iSession connection, use the same IP address you used for the iSession local endpoint. Otherwise, use any self IP address on the BIG-IP system.
  22. In the
    Local Address
    field, type the IPv6 address of the local BIG-IP device.
  23. In the
    Local Address
    field, type the IPv4 address of the BIG-IP device you are configuring.

    Local Address
    field, type
    0.0.0.0
    for an IPv4 network or
    ::

    Any
    .
    This entry means that you do not have to specify the IP address of the remote end of the tunnel, which allows multiple devices to use the same tunnel.
  32. For the
    Remote Address
    list, retain the default selection,
    Any
    .
  33. From the
    Remote Address
    list, select
    Specify
    , and type the IP address of the BIG-IP device at the other end of the tunnel.

    to
    65515
    .
  45. For the
    Use PMTU
    (Path MTU) setting, select or clear the check box.
    • If enabled and the tunnel MTU is set to
      0
      , the tunnel will use the PMTU information.
    • If enabled and the tunnel MTU is fixed to a non-zero value, the tunnel will use the minimum of PMTU and MTU.
    • If disabled, the tunnel will use fixed MTU or calculate its MTU using tunnel encapsulation configurations
    .
  46. From the
    TOS
    list, select
    Preserve
    , or select
    Specify
    and type a Type of Service (TOS) value.

    • Choose
      Disabled
      if you want to disable auto last hop behavior for this tunnel only.
