Load Balancing to IPv6 Nodes

Overview: Load balancing to iPv6 nodes

To set up the BIG-IP® system to function as an IPv4-to-IPv6 gateway, you create a load balancing pool consisting of members that represent IPv6 nodes. You also create a virtual server that load balances traffic to those pool members.
As an option, you can use the
tmsh
 command line interface to configure the BIG-IP system to send out ICMPv6 routing advisory messages, and to respond to ICMPv6 route solicitation messages. When you perform this task, the BIG-IP system begins to support auto-configuration of downstream nodes. Also, the downstream nodes automatically discover that the BIG-IP system is their router.

Task summary for load balancing to IPv6 nodes

When you configure IPv4-to-IPv6 load balancing, you must create a pool for load balancing traffic to IPv6 nodes, and then create an IPv4 virtual server that processes application traffic.

Creating a load balancing pool

The first task in configuring IPv4-to-IPv6 load balancing is to create a pool to load balance connections to IPv6 nodes. Use the Configuration utility to create this pool.
  1. On the Main tab, click
    Local Traffic
    Pools
    .
    The Pool List screen opens.
  2. Click
    Create
    .
    The New Pool screen opens.
  3. In the
    Name
     field, type a unique name for the pool.
  4. For the
    Health Monitors
     setting, in the
    Available
     list, select a monitor type, and click
    <<
     to move the monitor to the
    Active
     list.
    Hold the Shift or Ctrl key to select more than one monitor at a time.
  5. From the
    Load Balancing Method
     list, select how the system distributes traffic to members of this pool.
    The default is
    Round Robin
    .
  6. For the
    Priority Group Activation
     setting, specify how to handle priority groups:
    • Select
      Disabled
       to disable priority groups. This is the default option.
    • Select
      Less than
      , and in the
      Available Members
       field type the minimum number of members that must remain available in each priority group in order for traffic to remain confined to that group.
  7. Using the
    New Members
     setting, add each resource that you want to include in the pool:
    1. (Optional) In the
      Node Name
       field, type a name for the node portion of the pool member.
    2. In the
      Address
       field, type an IP address.
    3. In the
      Service Port
       field, type a port number, or select a service name from the list.
    4. (Optional) In the
      Priority
       field, type a priority number.
    5. Click
      Add
      .
  8. Click
    Finished
    .
The load balancing pool appears in the Pools list.

Creating a virtual server for IPv6 nodes

You can define a virtual server that references the pool of IPv6 nodes.
  1. On the Main tab, click
    Local Traffic
    Virtual Servers
    .
    The Virtual Server List screen opens.
  2. Click
    Create
    .
    The New Virtual Server screen opens.
  3. In the
    Name
     field, type a unique name for the virtual server.
  4. In the
    Destination Address/Mask
     field, type the IPv6 address in CIDR format.
    The supported format is address/prefix, where the prefix length is in bits. For example, an IPv6 address/prefix is
    64:ff9b::/64
     or
    2001:ed8:77b5:2::/64
    .
  5. In the
    Service Port
     field:
    • If you want to specify a single service port or all ports, confirm that the
      Port
       button is selected, and type or select a service port.
    • If you want to specify multiple ports other than all ports, select the
      Port List
       button, and confirm that the port list that you previously created appears in the box.
  6. In the Resources area of the screen, from the
    Default Pool
     list, select the name of the pool that contains the IPv6 servers.
  7. Click
    Finished
    .
The virtual server that references the pool of IPv6 nodes appears in the Virtual Servers list.
