LTM Question

I received a request to have 2 VIP addresses (2 virtual servers) that will have the same pool, the pool will have 2 members. The part I am unsure of is that the pool will need to really use one pool ...

The active/standby condition can be accomplished by enabling "Priority Group Activation" and selecting "less than... 1 Available Members" in the pool members pane properties. On pool member 192.168.11.5, assign a priority of 2. On 192.168.11.6, assign a priority of 1. As long as 192.168.11.5 is healthy, the LTM will only serve connections to it. If it gets marked down, the LTM will serve connections to 192.168.11.6 (assuming it is available).

 

As for the https/http issue, you can have one VIP that terminates SSL, and another VIP that listens on port 80. They both can send to the same pool using port 80 (or whatever you want). It all depends on your particular use-case. For most of my websites that serve https, I have the 2 VIPs described above, but the port 80 VIP does nothing more than send a 301 redirect to https (via iRule).
