How to inherit a generic irules?

Here is an easy solution which works perfectly to my expection.

 

 

Create 1 irules for each webserver

 

server1-rules

 

when DNS_REQUEST {

 

set pool4 "server1-pool-v4"

 

set pool6 "server1-pool-v6"

 

}

 

 

 

I already created generic-v6-irules

 

when DNS_REQUEST {

 

if {[DNS::rrtype] eq "A" and [active_members $pool4] > 0} {

 

pool $pool4

 

} elseif {[DNS::rrtype] eq "AAAA" and [active_members $pool6] > 0} {

 

pool $pool6

 

}

 

}

 

 

Then apply both server1-rules and generic-v6-irules to the wide IP.

 

(server1-rules needs to be in front of generic-v6-irules. so pool4 and pool6 are defined)
