I rule

Can some give me an Irule to loadbalance multiple pools for the same VIP

 

pool x 443 would be default

 

Pool y 5222

 

pool z 5223

    In my scenario we are planning to have a WILDCARD VIP for laodbalacning services 443 , 5222 & 5223 so if i create a simple TCP profile and use this Irule mentioed above would it work

    yes.

    this is another example using switch.
