Abstract

   There are a number of current and prospective requirements to
   indicate properties of nicknames, labels, and blocks thereof, for use
   with the TRILL (Transparent Interconnection of Lots of Links, RFC
   6325) protocol. To meet that need, this document specifies IS-IS
   (Intermediate System to Intermediate System) sub-TLVs and some of
   their uses.

1. Introduction

   There are a number of current and prospective requirements to
   indicate properties of Nicknames, data Labels, and blocks thereof,
   for use with the TRILL (Transparent Interconnection of Lots of Links
   [RFC6325]) protocol. To meet that need, this document specifies two
   IS-IS (Intermediate System to Intermediate System [ISO-10589]
   [RFC1195]) sub-TLVs and some of their uses.

   These sub-TLVs are used to flag properties of Nicknames and data
   Labels. Provision is made for flags associated with

      o  individual Nicknames,
      o  blocks of Nicknames,
      o  individual Labels, and
      o  blocks of Labels.

   In addition, different sizes of Nicknames and data Labels can be
   accommodated.

   The sub-TLVs specified in this document are used as follows:

   o  They appear only in the IS-IS Router Capability and MT-Capability
      TLVs, which are TLVs number 242 and 144 and are specified in
      [RFC4971] and [RFC6329] respectively.

   o  They can appear multiple times in the same or different Capability
      or MT-Capability TLVs.

1.1 Conventions Used in This Document

   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 [RFC2119].

2. The Nickname Properties Sub-TLV

   The structure of the Nickname properties (NICK-PROP) sub-TLV is as
   shown below.

         +-+-+-+-+-+-+-+-+
         | Type = TBD    |                (1 byte)
         +-+-+-+-+-+-+-+-+
         | Length        |                (1 byte)
         +-+-+-+-+-+-+-+-+-+-+-+-+...
