Configuring Dynamic 802.1Q VLANs
You can configure the router to dynamically create VLANs when a client accesses an
interface and requests a VLAN ID that does not yet exist. When a client accesses a
VLAN interface, the router instantiates a VLAN dynamic profile that you have
associated with the interface. Using the settings in the dynamic profile, the router
extracts information about the client from the incoming packet (for example, the
interface and unit values), saves this information in the routing table, and creates a
VLAN or stacked VLAN ID for the client from a range of VLAN IDs that you configure
for the interface.
Dynamically configuring VLANs or stacked VLANs requires the following general
steps:
1.
2.
3.
4.
For procedures on how to configure dynamic VLANs and dynamic stacked VLANs
for client access, see the JUNOS Subscriber Access Configuration Guide.
802.1Q VLAN IDs and Ethernet Interface Types
You can partition the router into up to 4095 different VLANs—depending on the
router model and the physical interface types—by associating logical interfaces with
specific VLAN IDs.
VLAN ID 0 is reserved for tagging the priority of frames. VLAN IDs 1 through 511
are reserved for normal VLANs. VLAN IDs 512 and above are reserved for VLAN
circuit cross-connect (CCCs).
For Gigabit Ethernet IQ interfaces and Gigabit Ethernet PICs with SFPs (except the
10-port Gigabit Ethernet PIC and the built-in Gigabit Ethernet port on the M7i router),
you can configure flexible Ethernet services encapsulation on the physical interface.
With flexible Ethernet services encapsulation, VLAN IDs from 1 through 511 are no
longer reserved for normal VLANs.
Table 55 on page 620 lists VLAN ID range by interface type.

Configuring Dynamic 802.1Q VLANs
Configure a dynamic profile for dynamic VLAN or dynamic stacked VLAN creation.
Associate the VLAN or stacked VLAN dynamic profile with the interface.
Specify the Ethernet packet type that the VLAN dynamic profile accepts.
Define VLAN ranges for use by the dynamic profile when creating VLAN IDs.
