Configuring a Normalized VLAN for Translation or Tagging

Implicit VLAN Translation to a Normalized VLAN

This topic provides configuration and operational information to help you manipulate
virtual local area networks (VLANs) within a bridge domain or a virtual private LAN service
(VPLS) instance. The VPLS configuration is not covered in this topic. For more information
about configuring Ethernet pseudowires as part of VPLS, see the
NOTE: This topic is not intended as a troubleshooting guide. However, you
can use it with a broader troubleshooting strategy to identify Juniper Networks
MX Series 3D Universal Edge Router network problems.
The manipulation of VLANs within a bridge domain or a VPLS instance can be done in
several ways:
By using the statements at the
vlan-map
does not use vlan-map . For more information about VLAN maps, see the
Network Interfaces Configuration Guide
By using statements within a bridge domain or VPLS instance hierarchy. This
vlan-id
method is used in the configuration in this chapter.
The vlan-id and vlan-tags statements under the bridge domain or VPLS routing instance
are used to:
Translate (normalize) received VLAN tags, or
Implicitly create multiple learning domains, each with a "learn" VLAN.
The use of a VLAN map or a normalized VLAN is optional.
NOTE: You cannot use

The VLAN tags of a received packet are compared with the normalized VLAN tags
specified with either the vlan-id
packet are different from the normalized VLAN tags, then appropriate VLAN tag operations
(such as push-push, pop-pop, pop-swap, swap-swap, swap, and others) are implicitly
made to convert the received VLAN tags to the normalized VLAN tags. For more
information about these operations, see the
