Configuring a Normalized VLAN

The following factors are important when configuring a normalized VLAN:

Use either the vlan-id vlan-number statement (to tag all packets with one normalized VLAN tag) or the vlan-tags outer outer-vlan-number inner inner-vlan-number statement (to tag all packets with the normalized outer and inner VLAN tags) if you want to tag packets sent onto the VPLS pseudowires.
Use the vlan-id none statement to remove the incoming VLAN tags identifying a Layer 2 logical interface when packets are sent over VPLS pseudowires. This statement is also used to configure shared VLAN learning.

Note: The outgoing packets can still contain customer VLAN tags.
If integrated routing and bridgling (IRB) is configured for a bridge domain or a VPLS routing instance, then you must configure a normalized VLAN using one of the following statements:
- vlan-id vlan-number
- vlan-id none
- vlan-tags outer outer-vlan-number inner inner-vlan-number
Use the vlan-id all statement to configure bridging for several VLANS with minimal amount of configuration and switch resources. See One VPLS Instance for Several VLANs for an example of this configuration.
