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

   The BIER TE YANG model includes BIER TE adjancency configuration and
   forwarding items configuration.  Some features can also be used to
   enhance BIER TE function, like ECMP and FRR.
