1.  Introduction

   Bierv6 provides stateless bier multicast service over Ipv6 , which is
   defined in [I-D.xie-bier-ipv6-encapsulation].  This draft specifies
   YANG data model for Bierv6.

2.  Terminologies

   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].

   Bier: Bit indexed explicit replication, referring to [RFC8279] and
   [RFC8296].

   Bierv6: Bit indexed explicit replication using IPv6 data plane,
   referring to [I-D.xie-bier-ipv6-encapsulation].

3.  Considerations

   Based on the Bierv6 design, the following attributes are necessary
   for Bierv6 configuration, besides the current parameters defined in
   [I-D.ietf-bier-bier-yang]:

   o  Bierv6 address block

Geng, et al.            Expires December 20, 2020               [Page 2]
Internet-Draft                    draft                        June 2020

   Ipv6 address block which are used for End.BIER allocation and ACL
   configuration for BIERv6 boundary.  Bierv6 address block could be
   part of SRv6 locater, or it could also be defined independently.

   o  End.Bier

   Ipv6 address indicating Bierv6 forwarding behavior, coming from
   Bierv6 address block.

4.  Bierv6 YANG Tree
