What can distinguish a multi-layer switch from a typical router is that the switch can perform some of the functions at the hardware level rather than software. This makes the switch more of a workhorse when it comes to high volume operations or speedy convergance. Having a switch run at layer 3 also negates the need for spanning tree and introduces load balancing... there you go for brief,
