NimbostratusiRule Load Balancing Pool
Hello community,
I need to know if it is possible with an irule to have a load balance with a different group, for example:
Pool1 / Member Pool / Server1 Pool2 / Member Pool / Server1 Pool3 / Member Pool / Server1 Pool4 / Member Pool / Server1
Pool5 / Member Pool / Server2 Pool6 / Member Pool / Server2 Pool7 / Member Pool / Server2 Pool8 / Member Pool / Server2
The client connects to a virtual server with a tcp 13000 port and I need to distribute the load first in Pool 1, the Second Pool 2, the third Pool 3 and the Fourth Pool 4, in these 4 Pool have the same Server Node1.
Then, the client connections go to Pool5, Pool6, Pool7 and Pool8, in theses 4 Pools have the same Server Node2.
Then the 8 connections the cycle the connections must be Pool 1, Pool 2, Pool 3, Pool 4, Pool5, Pool6, Pool7 and Pool8.
Somebody can help with this iRule, Please.

Not sure what you are trying to achieve. Certainly you can manipulate SLB options with iRule. You may also think of round-robin or ratio option for pool member selection.
Edward_Gastón_SHello community I can solved the irule and i share my irule
