NOTEThe editing instructions contained in this amendment define how to merge the material contained therein into the existing base standard and its amendments to form the comprehensive standard. This amendment specifies changes to IEEE Std 802.1Q that specifies a replacement for the GARP, GMRP, and GVRP protocols. Changes are applied to the base text of IEEE Std 802.1Q-2005 as modified by IEEE Std 802.1adTM-2006. Text shown in bold italics in this amendment defines the editing instructions necessary to changes to this base text. Three editing instructions are used: change, delete, and insert. Change is used to make a change to existing material. The editing instruction specifies the location of the change and describes what is being changed. Changes to existing text may be clarified using strikeout markings to indicate removal of old material, and underscore markings to indicate addition of new material). Delete removes existing material. Insert adds new material without changing the existing material. Insertions may require renumbering. If so, renumbering instructions are given in the editing instruction. Editorial notes will not be carried over into future editions of IEEE Std. 802.1Q. 1. Overview 1.1 Scope Insert the following text at the end of this subclause, renumbering the list items appropriately: In addition, this standard specifies protocols, procedures, and managed objects to support the Multiple Re
