LTM using own VIP as a pool member

Hi, My customer has an environment that needs to work in the flow below:

LTM
VIP1: 177.x.x.x:443
  Pool: ltm_frontend_pool > Priority Group Activation: Less than 1
  members:
    10.40.1.1:80 priority 10
    10.50.1.1:8443 priority 0

VIP2: 10.50.1.1:8443
   Pool: ltm_backend_pool
   members:
     10.x.x.x:443 backend servers

ASM VIP
VIP1: 10.40.1.1:80
  Pool: asm_frontend_pool
  members:
      10.50.1.1:8443

VIP1 LTM (client ssl) >> SNAT >> VIP1 ASM >> SNAT >>  VIP2 LTM >> (server ssl) >> servers

(A little bit confused, sorry!)

When ASM is up, its all OK. But when ASM bypass in priority group, the problem occurs, the VIP2 inside ltm_frontend_pool do not responds. In some F5 solution, I read that VIP in the same equipment not responds arp. So, we need to use the statement "virtual" in irule.

I did the irule bellow and it works fine.

Finally my question is: In the scenary above, has another way, maybe more simple, to solve this case?

iRule:

dg_ltm_forced_vips => contains de LTM VIP and port to be forced LTM backend.
dg_ltm_forced_failed_vips => contains de ASM VIP and port to be forced reselect LTM backend.

when HTTP_REQUEST {

 Check the first active member of default pool
 If the VIP is its own virtual server address, it needs to be forced to navigate into the second VIP of the same LTM equipment

set memberList [active_members -list [LB::server pool]]
log local0. "Active members: $memberList"

set vip [concat [lindex [lindex $memberList 0] 0]:[lindex [lindex $memberList 0] 1]]
log local0. "===========> First VIP: $vip"

 Check the vip in the list
set virtual_name [class match -value $vip equals dg_ltm_forced_vips]

if { $virtual_name ne "" } {
    log local0. "=========== set virtual ltm: $virtual_name"
    virtual $virtual_name
}

unset vip
unset virtual_name
}

when LB_SELECTED  {
log local0. "===========> Selected server: [LB::server addr]:[LB::server port]"
}

when LB_FAILED {
log local0. "=========== Failed server: [LB::server addr]:[LB::server port]"

 if server failed, reselect according the list
set virtual_name [class match -value [concat [LB::server addr]:[LB::server port]] equals dg_ltm_forced_failed_vips]
if { $virtual_name ne "" } {
    log local0. "=========== reselect virtual ltm: $virtual_name"
    LB::reselect virtual $virtual_name
}
}
