GTM Datacenter Failover when external link is dead

I have two datacenters with a gtm and pair of LTMs in each location.

 

I want to monitor my upstream provider to check to see if the external link is up or down.

 

If it is up, I would like to trigger a disable on that datacenter or resources so it goes to the other data center.

 

What would I need to use to accomplish this?

 

application delivery
BIG-IP DNS

    you have to create multiple gateway_icmp monitors with

     

    • monitor_icmp_8.8.8.8

       

      • alias address : 8.8.8.8
      • transparent : checked

    • monitor_icmp_8.8.4.4

       

      • alias address : 8.8.4.4
      • transparent : checked

    ...

     

    create enough monitor to make sure this is not the remote web site which fails but the link

     

    in your link, enable all these monitor with a minimum of 2 monitor (1 icmp + bigip_link)
