The simple intranet implementation is commonly found in a corporate intranet (see the following illustration). In this implementation, the BIG-IP® system performs load balancing for several different types of connection requests:
As the illustration shows, the non-intranet connections are handled by wildcard virtual servers; that is, servers with the IP address 0.0.0.0. The wildcard virtual server that is handling traffic to the cache servers is port specific, specifying port 80 for HTTP requests. As a result, all HTTP requests not matching an IP address on the intranet are directed to the cache server. The wildcard virtual server handling non-HTTP requests is a default wildcard server. A default wildcard virtual server is one that uses only port 0. This makes it a catch-all match for outgoing traffic that does not match any standard virtual server or any port-specific wildcard virtual server.
To create this configuration, you need to complete these tasks.
