    abstract =  {This memo defines a new Relay Agent Subscriber-ID option for the Dynamic Host Configuration Protocol for IPv6 (DHCPv6). The option allows a DHCPv6 relay agent to associate a stable "Subscriber-ID" with DHCPv6 client messages in a way that is independent of the client and of the underlying physical network infrastructure. {[}STANDARDS-TRACK{]}},
