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.
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.
