A router more intelligence capabilities than a bridge because it can handle several levels of addressing.It keeps a map of the entire network,including all the devices operating at or below its own protocol level.Whereas a bridge only checks the packet address to see if it is bound for another network,a router looks deeper.Referring to its network map,it examines the status of the different paths to destination and chooses the best method of getting the packet to the addressee.
