vlan-id-list (Ethernet VLAN Circuit)

 

Syntax

Hierarchy Level

Release Information

Statement introduced in Junos OS Release 9.5.

Description

Binds a single-tag logical interface to a list of VLAN IDs. Configures a logical interface to receive and forward any tag frame whose VLAN ID tag matches the list of VLAN IDs you specify.

Note

When you create a circuit cross-connect (CCC) using VLAN-bundled single-tag logical interfaces on Layer 2 VPN routing instances, the circuit automatically uses ethernet encapsulation. For Layer 2 VPN, you need to include the encapsulation-type statement and specify the value ethernet at either of the following hierarchy levels:

  • [edit routing-instances routing-instance-name protocols l2vpn]

  • [edit logical-systems logical-system-name routing-instances routing-instance-name protocols l2vpn]

For more information about the encapsulation-type configuration statement and the Layer 2 encapsulation types ethernet and ethernet-vlan, see the Junos OS VPNs Library for Routing Devices.

Options

[vlan-id vlan-idvlan-id]—A list of valid VLAN ID numbers. Specify the VLAN IDs individually by using a space to separate each ID, as an inclusive list by separating the starting VLAN ID and ending VLAN ID with a hyphen, or as a combination of both.

Range: 1 through 4094. VLAN ID 0 is reserved for tagging the priority of frames.

Note

Configuring vlan-id-list with the entire vlan-id range is an unnecessary waste of system resources and is not best practice. It should be used only when a subset of VLAN IDs (not the entire range) needs to be associated with a logical interface. If you specify the entire range (1-4094), it has the same result as not specifying a range; however, it consumes PFE resources such as VLAN lookup tables entries, and so on.

The following examples illustrate this further:

  • Inefficient

  • Best Practice
