Configuring a Layer 2 Virtual Switch with a Layer 2 Trunk Port
You can associate one or more Layer 2 trunk interfaces with a virtual switch. A Layer 2 trunk interface enables you to configure a logical interface to represent multiple VLANs on the physical interface. Within the virtual switch, you configure a bridge domain and VLAN identifier for each VLAN identifier configured on the trunk interfaces. Packets received on a trunk interface are forwarded within a bridge domain that has the same VLAN identifier. Each virtual switch you configure operates independently and can participate in a different Layer 2 network.
A virtual switch configured with a Layer 2 trunk port also supports IRB within a bridge domain. IRB provides simultaneous support for Layer 2 bridging and Layer 3 IP routing on the same interface. Only an interface configured with the interface-mode (access | trunk) statement can be associated with a virtual switch. An access interface enables you to accept packets with no VLAN identifier. For more information about configuring trunk and access interfaces, see the Junos® OS Network Interfaces.
In addition, you can configure Layer 2 learning and forwarding properties for the virtual switch.
To configure a virtual switch with a Layer 2 trunk interface, include the following statements:
 | Note: You must configure a bridge domain and VLAN identifier for each VLAN identifier configured for the trunk interface. |
