1.  Introduction

   [I-D.eckert-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.

2.  Design of the Data Model

   Instead of using respective sub-domain-id, si and bsl information
   like in BIER yang draft [I-D.ietf-bier-bier-yang], this document
   tries to group these sub-domain-id, si and bsl information in a new
   bier-common grouping to simplify the reference.  Later yang modules
   may import the common grouping easily.  Further, if this optimization
   is recognized, then BIER yang draft [I-D.ietf-bier-bier-yang] will be
   updated to group these sub-domain-id, si and bsl information as well.
