8-port Gigabit Ethernet Switch User's Guide
In this example, the VLAN definitions are extended to switches A and B. This gives only a single blocked port per VLAN

Impact of Layer 3 Switching.
The IP routing operational mode of the DGS-3308FG/DGS-3308TG 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.
