PPP provides a standard method for transporting multiprotocol datagrams over a
point-to-point link. PPP uses the High-Speed Data Link Control (HDLC) protocol for its
physical interface and provides a packet-oriented interface for the network-layer
protocols.
Internet Protocol Control Protocol (IPCP) (which negotiates for transport of IP version
4 datagrams), IPv6CP (which negotiates for transport of IP version 6 datagrams), the
OSI Network Layer Control Protocols (OSINLCPs), and Multiprotocol Label Switching
(MPLS) run within PPP.
The router supports dynamic PPP interfaces. For details, see "Configuring Dynamic
Interfaces" on page 511.
The software restricts the use of the general HDLC protocol (RFC 1662) to unnumbered
mode:
HDLC address field is 0xFF (all stations)
