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.
