How can I automatically mark pool addresses down when one ISP fails with GTM acting as Link Controller with multiple ISP's?

Hi,

I have a similar issue. I kind of managed to get it working using :

• links with custom monitors (based on gateway ICMP) pinging google DNS servers via the link.
• explicit-link-name to explicitly attach the link to each GTM virtual server associated with the ISP link. (see Sol13827)

   

  It works fine with two remaining issues :

   

• in my case, some virtual servers are automatically attached to the link (even though I did not specify an "explicit-link-name" value) because they belong to the same subnet. So I'll have to create another link and attach them to it.
• I still have one virtual server that does not follow the status of the link although it is configured in a similar way. I.e the link is marked as down, most virtual servers associated with the link are brought down, but this particular one stays up. Looks like a bug to me, and I have an open case with F5.

   

  Also what bugs me is that all service provisioning can be done from the WebUI, but the "explicit-link-name" needs to be done in TMSH... not optimal.

   

  Your last post on this topic was 3 weeks ago. Did you manage to get it working ? Is there anything you can share ?

   

  Thanks
