Configuring Dual VLAN Tags

To configure dual VLAN tags on a logical interface, include the vlan-tags statement:

vlan-tags inner <tpid.>vlan-id outer <tpid.>vlan-id;

You can include this statement at the following hierarchy levels:

[edit interfaces interface-name unit logical-unit-number]
[edit logical-systems logical-system-name interfaces interface-name unit logical-unit-number]

The outer tag VLAN ID range is from 1 through 511 for normal interfaces, and from 512 through 4094 for VLAN CCC or VLAN VPLS interfaces. The inner tag is not restricted.

You must also include the stacked-vlan-tagging statement in the configuration. See Examples: Stacking and Rewriting Gigabit Ethernet IQ VLAN Tags.
