Hi,

 

  • Source address affinity uses client address as persistence key.
  • destination address affinity uses server address as persistence key.

on a VS defined with one destination IP address, if using Destination address affinity, the persistence will use VS address as persistence key. all users will be redirected to the same pool member. This persistence may not be used for server load balancing.

 

Destination address affinity is used with forwarding virtual servers balancing connections to different routers in a pool (ex : Link controller). in such deployment, you may want that connections to the same server are routed on the same link.
