source_address persistance question

having a VIP with source_addr persistence

 

what we are wanting to do:

 

if address 10.0.0.0/8 hits the VIP then we want source_addr persistence, but any other source address falls to default or round robin on the pool members.

 

do we need iRule for this or is there some way to configure it with profiles?

    What nitass is saying is correct. Basically if you set up your virtual to have no persistence enabled, then put an iRule in place to selectively enable persistence for whatever inbound client IPs you want, you can achieve selective persistence. It's pretty straight forward, but if you run into any problems or have any questions, ask here and I'm sure someone will jump on them for you.
