Use the vlan-id all statement to configure bridging for several VLANS with minimal

amount of configuration and switch resources. For an example of this configuration,

see “Example: Configuring One VPLS Instance for Several VLANs” on page 55.

Configuring Learning Domains for VLAN IDs Bound to Logical Interfaces

A learning domain is a MAC address database to which the MAC addresses are added

based on the normalized VLAN tags. The normalized VLAN tags associated with a learning

domain are always carried within packets sent over VPLS virtual interfaces.

To configure bridging for several VLANs using a minimal amount of configuration and

switch resources, use the vlan-id all configuration statement to implicitly configure

multiple learning domains for a bridge domain or VPLS instance:

•

For a logical interface with a single VLAN tag, the statement implicitly creates a learning

domain for each normalized VLAN of the interface.

•

For a logical interface with dual VLAN tags, the statement implicitly creates a learning

domain for each inner VLAN (normalized VLAN).

This topic provides a configuration example to help you effectively configure a network

of Juniper Networks MX Series Ethernet Services Routers for a bridge domain or virtual

private LAN service (VPLS) environment. The emphasis here is on choosing the normalized

virtual LAN (VLAN) configuration. The VPLS configuration is not covered in this chapter.

For more information about configuring Ethernet pseudowires as part of VPLS, see the

Junos OS Feature Guide.
