Dynamic GTM Load balance based on LTM pool members avilabilty

Hi All,

Can some one help me the requirement.

In normal condition, traffic is like this

User --- GTM --- GTM Load Balance (RR/ Ratio) to 2 LTM --

---LTM 1 ----Load balance to pool members (Least connection/ Ratio /RR) -----6 members in Pool online.

---LTM 2 ----Load balance to pool members (Least connection/ Ratio /RR) ----- 6 members in Pool online.

Traffic is now 50 - 50 on both LTM and pool members.

Used case: if 4 nodes down at LTM2 side pool members;

User --- GTM --- GTM Load Balance (RR/ Ratio) to 2 LTM --

---LTM 1 ----Load balance to pool members (Least connection/ Ratio /RR) -----6 members in Pool online.

---LTM 2 ----Load balance to pool members (Least connection/ Ratio /RR) ----- 2 members in Pool online.

Now in this case scenario , we are looking at GTM to look at pool members availability in respective LTM (1 &2) and do the traffic modification to be like 75 % to LTM1 and 25% LTM2.

Thanks

AK
