The Point-to-Point Protocol (PPP) provides a standard method of
encapsulating network-layer protocol information over
point-to-point links. PPP also defines an extensible Link Control
Protocol, and proposes a family of Network Control Protocols
(NCPs) for establishing and configuring different network-layer
protocols.
This document defines the method for sending IPv6 packets over PPP
links, the NCP for establishing and configuring the IPv6 over PPP,
and the method for forming IPv6 link-local addresses on PPP links.
It also specifies the conditions for performing Duplicate Address
Detection on IPv6 global unicast addresses configured for PPP
links either through stateful or stateless address
autoconfiguration.
This document obsoletes RFC 2472. [STANDARDS-TRACK]
