ConfiguringLearning Domains for VLAN IDs Bound to Logical Interfaces

Alearning domain is a MAC address database towhich the MAC addresses are added

basedonthe normalized VLAN tags. The normalized VLAN tags associatedwith a learning

domainare always carried within packets sentover VPLS virtual interfaces.

Toconfigure bridging forseveral VLANs using a minimal amount of configuration and

switchresources, use the vlan-id all configurationstatement to implicitly configure

multiplelearning domains for a bridge domain or VPLS instance:

•Fora logical interfacewith a single VLAN tag, the statementimplicitly creates a learning

domainfor each normalized VLAN of the interface.

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

domainfor each inner VLAN (normalized VLAN).

Thistopic provides a configuration exampleto help you effectively configure a network

ofJuniper Networks MX Series Ethernet Services Routersfor a bridge domain or virtual

privateLANservice (VPLS) environment. The emphasis hereis on choosing the normalized

virtualLAN (VLAN) configuration. The VPLS configurationis not covered in this chapter.

Formore information about configuring Ethernet pseudowires aspart of VPLS, see the

JunosOS Feature Guide.
