Amendment by IEEE, 06/22/2007

Full Description

Scope

In addition, this standard specifies protocols, procedures, and managed objects to support the Multiple Registration Protocol (MRP). MRP allows participants in an MRP Application to register attributes with other participants in a Bridged Local Area Network. Two applications are defined--one to register VLANs [Multiple VLAN Registration Protocol (MVRP)] and one to register MAC addresses [Multiple MAC Registration Protocol (MMRP)]. MVRP will furthermore provide for the rapid healing of network failures without interrupting services to unaffected VLANs. To this end, it specifies the following:a) MRP and the operation of the MRP protocol entities.1, 2b) The generic frame formats used in MRP protocol exchanges.c) The Multiple MAC Registration Protocol (MMRP) application of MRP, and the frame formats that ituses.d) The Multiple VLAN Registration Protocol (MVRP) application of MRP, and the frame formats thatit uses.

Purpose

The use of bridges by Ethernet Service Providers has greatly increased the number of VLANs and Group MAC Addresses in Provider Bridged Networks. The time and bandwidth required by the existing GVRP and GMRP protocols to register this information has become a dominant factor in the fault recovery time of a Provider Bridged Network. In a large network, localized topology changes can affect the service over a much larger portion of the network. This standard replaces GARP with MRP, greatly improving both situations.

Abstract

Amendment Standard - Superseded.This amendment specifies a set of protocols that replaces the GARP, GMRP, and GVRP protocols specified in earlier versions of IEEE Std 802.1Q.
