GTM: http+https and WideIP availability

Hi All, We are using 2x BIG-IP VM's (11.6) running in different datacentres with both GTM + LTM running on the same appliance. On each LTM we have two Virtual Servers (in LTM), one for HTTP...

Hi David!

We recently had the same scenario and it is a way to achieve that.

You do not know which service the client is preferring when the DNS request comes in (you do if you have different dns names for http and https). So you will have to decide which pool and thereby which VS health should be taken into account when GTM answers the DNS request.

You can however also include a dependency vs:

Create two VS in GTM – one with x.x.x.x:80 and one with x.x.x.x:443
On the x.x.x.x:443 VS you set a dependency virtual server – the x.x.x.x:80
Now you can create a GTM pool with just the x.x.x.x:443 server and assign it to the wideIP.

If either of the two monitored VSs goes down the next VS assigned in the pool will be used.

I hope that this helps you.
