f5 gtm continues respondig an IP after router goes down

Hello all,

A basic question for you.

I have configured listeners to load balance incoming traffic using 3 ISPs. I configured three listeners, but when I disconnected one router, F5 continues resolving the name with the IP in the network of the router i disconnected. Could yo explain me what I can do to overcome this? The monitor I am using with the router is icmp-gateway.

Thanks for your answers
