3.9.6 Example for Configuring Inter-Device MUX VLAN

Networking Requirements
An enterprise forbids communication between some departments and allows communication
between other departments. All employees in the enterprise are allowed to access certain servers.
The MUX VLAN function can be configured to meet the preceding requirements. The enterprise
needs to add the servers to the principal VLAN, add the hosts that are allowed to communicate
to a group VLAN, and add the hosts that need to be isolated to a separate VLAN. Employing
this function reduces the needed VLAN IDs.
When employees connect to servers through multiple AR3200s, inter-device MUX VLAN can
be configured.
As shown in
Ethernet2/0/5 are connected to PCs. The Routers use Ethernet2/0/6 to communicate with each
other. To meet the preceding requirements, the enterprise needs to perform the following
configurations on the Routers: configure VLAN 2 as a principal VLAN and add Ethernet2/0/1
to VLAN 2; configure VLAN 3 as a subordinate group VLAN and add Ethernet2/0/2 and
Ethernet2/0/3 to VLAN 3; configure VLAN 4 as a subordinate separate VLAN and add
Ethernet2/0/4 and Ethernet2/0/5 to VLAN 4. Configure Ethernet2/0/6 to allow VLAN 2, VLAN
3, and VLAN 4 to pass through.
