Bridging VLANs Across Multiple Switches
C and D was shut down to avoid such a loop. See
information about how Spanning Tree configures network topologies that are loop free.
The following diagram shows the same bridging domain example as seen by the end user workstations.
Because traffic between these workstations is bridged across physical switch connections within the
VLAN 10 domain, the workstations are basically unaware that the switches even exist. Each workstation
believes that the others are all part of the same VLAN, even though they are physically connected to
different switches.
Creating a VLAN bridging domain across multiple switches allows VLAN members to communicate with
each other, even if they are not connected to the same physical switch. This is how a logical grouping of
users can traverse a physical network setup without routing and is one of the many benefits of using
VLANs.
