LTM Source Address Persistence: Prefix Length Guideline

Hi all. I would like to understand the impact of using source address persistence on LTM module. By default is using /32 prefix length. I am thinking of changing this to /24 to reduce big ip persist...

Hello ciscozest!

 

Never heard of it. As you said, I think the biggest impact could be in your application. For the VE it would be - if any - a better impact since the table would go down.

 

Just take make sure that in this /24 there's no users coming from behind a proxy/nat or something... You could potentially balance a lot to a specific node/pool member.

 

Cheers!
