Juniper JUNOS OS 10.4 User Manual

switched within the interfaces listed within bridge domain accounting and any statically
configured trunk interfaces and are prevented from crossing the VPLS pseudowire due
to the absence of VLAN 30 on the trunk.
Configuration of Tag Translation Using Dynamic Profiles
Consider a final case where the bridge domain VLANs need translation at the VPLS
pseudowire trunk interface. In this case, sales (VLAN 10) is mapped to VLAN 110 and
engineering (VLAN 20) is mapped to VLAN 120.
This configuration adds tag translation to the VPLS pseudowire traffic.

NOTE: This is not a complete router configuration.
This translates the sales and engineering VLAN tags egressing the VPLS pseudowire
accordingly. At the ingress of the VPLS pseudowire, VLANs 110 and 120 are translated
back to 10 and 20, respectively.
