2.8.5 Example for Configuring Remote Bridging with VLAN ID
Transparent Transmission
Remote bridging with VLAN ID transparent transmission allows the devices in the same VLAN
but different in locations to communicate with each other.
Networking Requirements
An enterprise has multiple departments in different locations. To allow the communication
between departments in different locations, remote bridging can be used. To allow users in the
same department (the same VLAN) to communicate with each other, while isolating users in
different departments (different VLANs), VLAN ID transparent transmission must be enabled.
As shown in Figure 2-12, User 1, User 2, User 3, and User 4 are on the same network segment.
User 1 and User 3 belong to a VLAN; User 2 and User 4 belong to the other VLAN. To allow
users in the same VLAN to communicate with each other and isolate users in different VLANs,
remote bridging and VLAN ID transparent transmission can be enabled. In this manner, User 1
can only communicate with User 3, and User 2 can only communicate with User 4.
