    abstract =  {The Point-to-Point Protocol (PPP) (RFC1661) provides a standard method for transporting multi-protocol datagrams over point-to-point links. PPP defines an extensible Link Control Protocol and a family of Network Control Protocols (NCPs) for establishing and configuring different network-layer protocols. This document extends the NCP for establishing and configuring the Internet Protocol over PPP (RFC1332), defining the negotiation of 6RD (RFC5969) Border Relay (BR) addresses. While the authors believe one could use DHCP INFORM (RFC2131) to obtain the necessary 6RD parameters, this is simply an alternative which allows reuse of an existing PPP-based configuration infrastructure.},
