Traffic shaping policy -default policy

Hi, lets say we have two subnets 192.168.1.0/24 and 192.168.2.0/24  Created a traffic shaping policy for 192.168.1.0/24  and set reverse shaper 25Mbps  (total is 50Mbps) suppose if we have not created  policy for  192.168.2.0/24  , what will happen to 192.168.2.0/24  in terms of  bandwidth  Thanks
