1.0 Introduction

   This document proposes rules for Top-Level Aggregation Identifiers
   (TLA ID) and Next-Level Aggregation Identifiers (NLA ID) as defined
   in [AGGR].  These proposed rules apply to registries allocating TLA
   ID's and to organizations receiving TLA ID's.

   This proposal is intended as input from the IPng working group to the
   IANA and Registries.  It is not intended for any official IETF
   status.  Its content represents the result of extensive discussion
   between the IPng working group, IANA, and Registries.

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in [RFC 2119].

2.0 Scope

   The proposed TLA and NLA assignment rules described in this document
   are intended for the first two years of IPv6 TLA address assignments.
   As routing technology evolves and we gain additional experience with
   allocating IPv6 addresses the procedures proposed in this document
   may change.
