DES-3326S Layer 3 Fast Ethernet Switch User’s Guide
Understanding and Troubleshooting the Spanning Tree Protocol 339
Impact of Layer 3 Switching.
The IP routing operational mode of the DES-3326S Layer 3
switch can accomplish the following:
• Building a forwarding table, and exchanging
information with its peers using routing protocols.
• 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.
