Configuring Bridge Domains as Switches for Layer 2 Trunk Ports
You can configure a set of bridge domains that are associated with a Layer 2 trunk port. The set of bridge domains function as a switch. Packets received on a trunk interface are forwarded within a bridge domain that has the same VLAN identifier. A trunk interface also provides support for IRB, which provides support for Layer 2 bridging and Layer 3 IP routing on the same interface.
To configure a Layer 2 trunk port and set of bridge domains, include the following statements:
For interface-mode trunk, you can include the vlan-id-list statement.
You must configure a bridge domain and VLAN identifier for each VLAN associated with the trunk interface. You can configure one or more trunk or access interfaces at the [edit interfaces] hierarchy level. 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.
