iRule for replying host unreacheable if pool memebers down.

Hi Aaron,

 

Downstream router is tracking ip address configured on f5 using icmp.Incase xx number of pool memners are down we would want downstream router to forward traffic to another site.IP tracking can only be done on icmp responses as per device limitation.

 

 

As per F5 support Virtual server always responds positively to icmp.

 

 

 

I was considering following.

 

Virtualserver 1.1.1.1:1(listen on icmp)

 

pool member 127.0.0.1

 

 

and then assign Irule

 

 

when client data if min members pool < 5

 

" send icmp host unrecheable"

 

 

 

I need actual irule statements for

 

sending icmp host unrecheable

 

 

 

Thx.
