DNS ISP monitoring

Question

In our network, we have two ISP's connected through two separate routers. F5's have the outside IP's routed directly to the F5 and are set up as VIP's. We would like to load balance some services from outside on two separate ISP WAN IP's. &nbsp;
So for instance, we have:
VIP ISP1: 1.1.1.1
VIP ISP2: 2.2.2.2&nbsp;
DNS/GTM is set that  points to 1.1.1.1 and 2.2.2.2.&nbsp;
How can we monitor the outside links on the GTM/DNS?&nbsp;
Thank you for your help,
Daniel&nbsp;

Hi&nbsp;
I guess you could try to define links, and then use explicit link assignment to the VS.
I haven't tried it myself, but it's documented in the KB &nbsp;
