Configuring ISP Load Balancing
Overview: ISP load balancing
You might find that as your network grows, or network traffic increases, you require an additional connection to the Internet. You can use this configuration to add an Internet connection to your existing network. The following illustration shows a network configured with two Internet connections.

Task summary for ISP load balancing
There are number of tasks you must perform to implement load balancing for ISPs.
Task list
Creating a load balancing pool
You can a create load balancing pool, which is a logical set of devices, such as
web servers, that you group together to receive and process traffic, to efficiently
distribute the load on your resources. Using this procedure, create one pool that load balances the content servers, and one pool to load balance the routers.
The load balancing pools appear in the Pools list.
Creating a virtual server for inbound content server traffic
You must create a virtual server to load balance inbound connections. The default pool that you assign as a resource in this procedure is the pool of internal servers.
The virtual server is configured to load balance inbound connections to the
servers.
Creating a virtual server for outbound traffic for routers
You must create a virtual server to load balance outbound connections. The default pool that you assign as a resource in this procedure is the pool of routers.
The virtual server is configured to load balance outbound connections to the
routers.
Creating self IP addresses an external VLAN
You must assign two self IP addresses to the external VLAN.
The self IP address is assigned to the external VLAN.
Enabling SNAT automap for internal and external VLANs
You can configure SNAT automapping on the BIG-IP system for internal and external
VLANs.
SNAT automapping on the BIG-IP system is configured for internal and external VLANs.
