persist source_addr

Hello,   I have question on understanding persistence source address on the F5. Does this apply to only when you create a session it will always maintain that session to the same backend node? Or ...
application delivery
BIG-IP
LTM

Connection attempt after the persistence timeout will be considered as a new connection instead of a returning connection. So in that scenario, your connection will load balanced as per the LB method.

    Thank you for the response. To follow up with that.. If I were to enable indefinite timeout on a new custom persistence sour_addr profile and the VIP learns the client IP address, will it always forwards it to the same backend server even with brand new connections from the same client IP?

    It would not be recommended to have indefinite persistence timeout as it would eat up device resources.

     

    But to answer your question yes..
