Stick tables are only synchronized on updates. Clearing or inserting values from the CLI are not updates but what I'd call local maintenance. In practice however, if you clear one LB's entry, the next time it'll get a request, it will load balance it, update the table and propagate the update. Also, if you're running with automatic expiration after a certain delay, both of your LB's tables will expire after inactivity. Regards, Willy
