vlan-id-list (Ethernet VLAN Circuit)
Syntax
vlan-id-list [vlan-id vlan-id–vlan-id];
Hierarchy Level
[edit interfaces interface-name unit logical-unit-number], [edit logical-systems logical-system-name interfaces interface-name unit logical-unit-number]
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.
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-id–vlan-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.
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
[edit interfaces interface-name] vlan-tagging; unit number { vlan-id-range 1-4094; }
Best Practice
[edit interfaces interface-name] unit 0;
Required Privilege Level
