Can you please provide your iRule.

 

You can apply both irule and default pool to virtual server or just iRule.

 

iRule will have high priority over default pool.

 

1st step is traffic flow according to the iRule and any traffic not matching iRule then it will go to default pool.

 

hope this helps.

when CLIENT_ACCEPTED { if { [IP::addr [IP::client_addr]/24 equals 10.10.1.1] } { pool Pool_X } }

 

And my default pool for VS is Pool_Y. Now suppose 10.10.1.1 makes a connection but Pool_X is down will it go to Pool_Y.
