Internet Engineering Task Force (IETF) F. Le Faucheur Request for Comments: 7256 R. Maglione Updates: 6320 Cisco Category: Standards Track T. Taylor ISSN: 2070-1721 Huawei July 2014 Multicast Control Extensions for the Access Node Control Protocol (ANCP) Abstract This document specifies the extensions to the Access Node Control Protocol (ANCP) (RFC 6320) required for support of the multicast use cases defined in the Access Node Control Protocol framework document (RFC 5851) and one additional use case described in this document. These use cases are organized into the following ANCP capabilities: o multicast replication initiated by the Network Access Server (NAS); o conditional access and admission control with white and black lists; o conditional access and admission control with grey lists; o bandwidth delegation; and o committed bandwidth reporting. These capabilities may be combined according to the rules given in this specification. This document updates RFC 6320 by assigning capability type 3 to a capability specified in this document and by changing the starting point for IANA allocation of result codes determined by IETF Consensus from 0x100 to 0x64.
