persistence type for ssh vip

All,

 

is it advisable to use cookie based persistence for ssh vip. currently we are using source ip based vip and due to this we are seeing load is going to one server. so we suspect this may be due to f5 sending new connection coming from same ip address one server only.

 

please suggest.

 

thanks

    You cannot use Cookie based persistence for SSH, because Cookies are a specific feature to HTTP protocol.

     

    With SSH, I think you have to use source IP persistence. I'm wondering, why do you need to use persistence? SSH connections tend to be long-lived, and If you're load-balancing some SSH servers, then I have to assume that it means each pool member is identical, and it doesn't matter which server the user connects to, which makes me wonder why you need persistence.
