May 26, 2011 · These requirements enable provider bridges to have the same functionality as Layer 2 protocol tunneling (L2PT) and Q-in-Q (QnQ) bridges. This document describes the IEEE 802.1ad implementation on Cisco switches using Layer 2 switch ports.
Dec 31, 2002 · 802.1ad - Provider Bridges. This amendment to IEEE Std 802.1Q-1998 is intended to develop an architecture and bridge protocols, compatible and interoperable with existing Bridged Local Area Network protocols and equipment, to provide separate instances of the MAC services to multiple independent users of a Bridged Local Area Network in a manner ...

IEEE 802.1ad Support on Provider Bridges. First Published: April 19, 2010. Last Updated: May 26, 2011. Service provider bridges (also called provider bridges) allow devices in a service provider network to transparently carry the Layer 2 control frames of a customer.
IEEE 802.1ad is an amendment to the IEEE 802.1Q-1998 networking standard which adds support for provider bridges. It was incorporated into the base 802.1Q standard in 2011. The technique specified by the standard is known informally as stacked VLANs or QinQ.
Dec 11, 2002 · Ethernet Data Encryption devices (EDEs) are specified in this amendment. An EDE is a two-port bridge that uses MACsec to provide secure connectivity for attached customer bridges, or for attached provider bridges. EDEs may allow the customer (or provider) bridges to continue to use a VLAN Identifier (VID) in transmitted frames to select
Oct 4, 2004 · Interconnect Provider Bridge (802.1ad) Networks in a manner that allows scaling of the Carrier Bridged Network to support at least 2^20 S-VLANs. Support at least 2^16 multipoint S-VLANs. Interconnect at least 256 Provider Bridged Networks.
The majority of these issues have been addressed in the IEEE 802.1ad standard for provider bridges and they can be leveraged for VPLS networks. This document extends the PE model described in [ RFC4664 ] based on the IEEE 802.1ad bridge module and illustrates a clear demarcation between IEEE bridge module and IETF LAN emulation module.
