Thefollowing happens on the C2 VLAN as a result of the vlan-idnone configuration:
AMAC table is created foreach instance of vlan-id none. All MAC addresses learned
overthe interfacesbelonging to this VPLS instanceare added to this table. The received
orconfigured VLAN tags are not considered when the MACaddresses are added to
thistable. This is a case of shared VLAN learning.
Packetswith a single VLAN tag valueof 301 are accepted on interface ge-1/0/0.11.The
VLANtag value 301 is then popped and removed from the frame of this packet.
Packetswith a single VLAN tag value of 302 areaccepted on interface ge-6/0/0.11.
TheVLAN tag value 302 is then popped and removed from the frameof this packet.
Allpackets sent on pseudowires will not have any VLAN tagsused to identify the
incomingLayer 2 logical interface.
NOTE: Thepacket can still contain other customerVLAN tags.
Packetsreceived from pseudowiresare looked up in the MAC table associatedwith
theVPLS instance. Any customer VLAN tags in the frame areignored.

Example:Configuring One VPLS Instance for Several VLANs
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.
NOTE: Thistopic does not present exhaustive configurationlistings for all
routersin the figures. However,you can use it with a broader configuration
strategyto completethe MX Series router network configurations.
Considerthe VPLS network shown in Figure 9 on page 56.
