DES-3326S Layer 3 Fast Ethernet Switch User’s Guide

Using layer 3 switches and IP routing eliminates the need for STP port blocking because the packets are routed by destination addresses. The link redundancy remains, and relying on the routing protocols gives a faster convergence than with STP.

The drawback is that the introduction of layer 3 switching usually requires a new addressing scheme.
