Persistent hash iRule

Hi All,

I have a question regarding the Persistent hash iRule.

Two Pool members are configured as Round robin.

Sessions have been concentrated as one pool member since we added the Persistent hash iRule below to the virtual server.

There are two Client IPs in total and have not changed since iRule was applied.

What is the reason? Please help me.

<Pool member#1 connection>

<Pool member#2 connection>

Thanks.
