In this post I will show how to do basic configuration of F5 LTM for load balancing traffic to hosted web servers. Following is the topology.
We have three server with IP as 192.168.4.131, 192.168.4.132, 192.168.4.133 . F5 LTM have a interface which have IP address as 192.168.4.130. Gateway of servers is 192.168.4.130
We will configured F5 to load balance traffic to 3 server. External user will use IP 192.168.2.135 and traffic will be sent to one of these server by F5 LTM.
You have to configure Node, Pool, Virtual server for this task.
1> Configuring Node: Node will represent actual server.
2> Configure pool: Now add all the node to one pool. You need to add nodes under Resources. Health monitor is optional but its good to check the health status of servers.
3> Configure Virtual server: Create a virtual server, assign a IP to virtual server to which user will hit and traffic will be redirect to actual server as per configuration.
