Transparent LAN Services (TLS)

Extended TLS and Double Tagging
The RDL-3000 may be configured to support combinations of double tagging and pass
though.
In this example, TLS traffic is extended across the wireless interface to remote locations.
The TLS packets are segregated from other traffic by creating a TLS Group specifying
the reserved VID. This solution allows unmodified traffic to be exchanged between
Network B and Network C (both Services are pass though). Tagged traffic from Network
B or Network C addressed to the TLS Network is double-tagged (Q-in-Q) and forwarded
to the TLS Network. Double-tagged packets from the TLS network that are addressed to
Network B or Network C have the outer tag removed when the packet is forwarded by
Network B or Network C.
