Receiving packets and forwarding them to the correct
interface based upon their destination address
With layer 3 switching, there is no performance penalty to
introducing a routing hop and creating an additional segment
of the network.
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.
