Revision of the standard to: Change the title of the standard to its original form, prior to the publication of the 1998 edition as an ISO/IEC standard; incorporate technical and editorial corrections, including those currently documented under P802.1y; incorporate existing published amendments (802.1t, 802.1w); remove the Spanning Tree protocol defined in Clause 8 and attendant textual corrections. Maintenance and removal of material that is now redundant. Revision Standard - Superseded. An architecture for the interconnection of IEEE 802(R) Local Area Networks (LANs) below the MAC Service boundary is defined. MAC Bridges, as specified by this standard, allow communications between end stations attached to separate LANs, each with its own separate MAC, to be transparent to logical link control (LLC) and network layer protocols, just as if the stations were attached to the same LAN.
