1.  Introduction

   [I-D.ietf-bier-te-arch] introduces an architecture for BIER-TE:
   Traffic Engineering for Bit Index Explicit Replication (BIER).  This
   document defines a YANG data model for BIER TE.  The content is in
   keeping with the TE architecture draft.  In addition, this YANG data
   model contains BIER TE frr items of [I-D.eckert-bier-te-frr].

2.  Design of the Data Model

   Because BIER-TE technology can be used independently, the common
   elements reference from BIER YANG ( [I-D.ietf-bier-bier-yang] ) is
   not suitable, such as subdomain-id, bitstringlength, set identifier,
   and so on.  These common elements should be defined in general BIER
   YANG model or in each YANG model respectively.  The BIER TE YANG
   model includes BIER TE forwarding items configuration.  Some features
   can also be used to enhance BIER TE function, like ECMP and FRR.
