DES-3326 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.
