•
Configure a VLAN dynamic profile. See the Subscriber Access Configuration Guide

•
Include the routing-instances statement along with the $junos-routing-instance
dynamic variable at the [edit dynamic-profiles profile-name interface
$junos-interface-name] hierarchy level.
•
Include the interfaces statement along with the $junos-interface-name dynamic
variable at the [edit dynamic-profiles profile-name interface “$junos-interface-name”
routing-instances “$junos-routing-instance”] hierarchy level.
•
Include the interfaces statement along with the $junos-interface-ifd-name dynamic
variable at the [edit dynamic-profiles profile-name] hierarchy level.
•
Include the unit statement along with the $junos-interface-unit dynamic variable at
the [edit dynamic-profiles profile-name interface “$junos-interface-ifd-name”]
hierarchy level.
•
(Optional) Include the encapsulation statement at the [edit dynamic-profiles
profile-name interface “$junos-interface-ifd-name” unit $junos-interface-unit] hierarchy
level and specify the unit encapsulation as vlan-vpls or vlan-ccc.
NOTE: If you choose not to specify an encapsulation for the logical
interface, you must specify encapsulation for the physical interface.
•
Include the vlan-tags statement and define the outer VLAN tag using the
$junos-stacked-vlan-id dynamic variable and the inner VLAN tag using the
$junos-vlan-id dynamic variable at the [edit dynamic-profiles profile-name interface
“$junos-interface-ifd-name” unit $junos-interface-unit] hierarchy level.
•
Include the input-vlan-map statement at the [edit dynamic-profiles profile-name
interface “$junos-interface-ifd-name” unit $junos-interface-unit] hierarchy level and
define the map settings as follows:
NOTE: You configure the input-vlan-map statement only when there is
a need to either push an outer tag on a single-tagged subscriber packet
or modify the outer tag in a subscriber dual-tagged packet.
•
Specify the action that you want the input VLAN map to take. See the Network
Interfaces Configuration Guide for details on how to configure input-vlan-map
statement options.
•
Include the vlan-id statement along with the $junos-vlan-map-id dynamic variable.
•
Include the output-vlan-map statement at the [edit dynamic-profiles profile-name
