Basic VIPs


Overview: 

There are three main players when working with the F5's.  The Virtual Server is the VIP or external IP address that traffic goes to.  It in turn points to a Pool (or multiple pools) that in turn has multiple servers or Members.


Create A Pool: 

The pool is simply a collection of real servers, how to monitor those servers, and the method to spray traffic over those servers.  

To create a new pool, under 
Main :: Local Traffic :: Virtual Servers :: Pools :: Pool List 
Select the "+" to create a new pool.  

Then in the new pool window, fill in the following fields: 
  1. Name: Enter a name for the pool
  2. Description: Add some description so you can remember what this is over any of the other pools
  3. LB Method: There are a bunch of different methods for balancing traffic.  For now, simply enter Round Robin.  
  4. New Members: For each real server, provide a description and either its IP or DNS name, 
  5. Add: Select the add button to save each defined New Member
  6. Finished: When you are done entering in all the New Members, enter Finished.  


Create a Virtual Server

A Virtual Server is the front end VIP that external traffic will go to.  The VS handles SSL certs, protocol conversion (ie: https to http), compression and any scripting like iRules.  

To create a new server, under 
    Main :: Local Traffic :: Virtual Servers :: Virtual Servers List
select the "+" icon to create a new VS

In the New Virtual Server window, enter in the following fields
  1. Name: Name of the Virtual Server
  2. Description: Description to remind you what this is used for
  3. Type: Standard.  Should be a normal web VS.  The other types are noted in sol14163.  
  4. Destination: The IP address of the VIP that external traffic should point to
  5. Service Port: The port that should be listening on the Destination IP.  (ie: 80=http, 443=https)
  6. HTTP Profile: Select HTTP Profile for basic web traffic 
  7. SNAT Pool: For internal routing.  Enable this if you want traffic to the servers to be sourced from the F5.  See more on this here. 
  8. Default Pool: Select the pool name you created in the "Create a Pool" section above
  9. Default Persistence Profile: Select if you want to enable stickiness.  See more here. 
  10. Finished: Select the finished button to save your changes.
