Hi Leo,

 

If I am reading this correctly, then you should also monitor the Tokyo LTM via the GTM pool

 

 

Then you could then re-write the irule as the following:

 

 

when DNS_REQUEST {

 

if { [active_members pool_tokyo] == 0 } {

 

host 1.1.2.10

 

} else {

 

if { [DNS::rrname] eq "www.wip.leo-d.com" } {

 

host 1.1.1.10

 

}

 

}

 

}

 

 

I haven't tested this out but hopefully this works for you
