irules is conflicting with last resort pool

Here is our wideip configuration

 

wideip {

 

name "www.test.com"

 

alias "test.com"

 

pool_lbmode rr

 

partition "Common"

 

last resort pool "last-test-pool"

 

pool "www-test-pool"

 

pool "www-test-pool-v6"

 

rule "test-ipv6-irule"

 

}

 

 

The following irules handles A and AAAA requests. But it returns last-test-pool in stead of www-test-pool for A request. (I guess it's because "last resort pool" is above other pools in the configuration)

 

should we just add logic of "last resort pool" in the irules and get rid of "last resort pool" configuration? any suggestions? Thanks very much.

 

 

when DNS_REQUEST {

 

set DEBUG 0

 

 

if { $DEBUG } { log local0. "RRtype [DNS::rrtype], WIP [wideip name], Pools [pools -list]" }

 

 

Ensure no pool selected from a previous request

 

unset -nocomplain selected_pool

 

 

if {[DNS::rrtype] eq "A"} {

 

set selected_pool [lsearch -inline -not [pools -list green] *v6]

 

 

} elseif {[DNS::rrtype] eq "AAAA"} {

 

set selected_pool [lsearch -inline [pools -list green] *v6]

 

}

 

if { [info exists selected_pool] and not [string equal "" $selected_pool] } {

 

if { $DEBUG } { log local0. "Selecting $selected_pool" }

 

pool $selected_pool

 

}
