Question about when L3 sticky information is removed on CSS

Hi everyone,

I have a question about L3 sticky on CSS.

I understand L3 sticky takes effect on the following situations,

1: until expiring inactive timer

2: until sticty table full

and

3: until the connection disconnect by receiving RST or FIN from client or real server

The "3:" means that CSS maintains sticky connection between specific client IP address

to real server (L3 stickty) when CSS has its information on sticky table.

And CSS has removed it from sticky table if CSS receive RST or FIN even if the inactive timer

abot its connection has not expired.

That is, CSS removed L3 sticky information from sticky table when CSS receive

RST or FIN from client or real server even if inactive timer has not expired and

in this situation, the next new connection from same client IP address is processed with

normal load balancing, in the result, the new connection from same client IP address

forwards other real server.

Is my understanding correct ?

Or CSS maintains L3 sticky information on the sticky table until the situation meets

"1:" or "2:" even if CSS receive RST or FIN ?

Your information would be appreciated.

Thank you in advance.

Best Regards,

What point number 3 means is the layer 3 sticky will take effect when a connection disconnect message is received from a client or a real server. This connection disconnect is received in the form of RST or FIN messages from the real server or the client.
