PPP(4) BSD Kernel Interfaces Manual PPP(4)
NAME
ppp -- point to point protocol network interface
SYNOPSIS
options PPP_BSDCOMP
options PPP_DEFLATE
options PPP_FILTER
pseudo-device ppp
DESCRIPTION
The ppp interface allows serial lines to be used as network interfaces using the Point-to-Point Protocol (PPP). The ppp interface can use
various types of compression and has many features over the SLIP protocol used by the sl(4) interface.
Supported options are:
options PPP_BSDCOMP Enable support for BSD-compress (`bsdcomp') compression in ppp.
options PPP_DEFLATE Enable support for deflate compression in ppp.
options PPP_FILTER This option turns on pcap(3) based filtering for ppp connections. This option is used by pppd(8) which needs to be
compiled with PPP_FILTER defined (the current default).
DIAGNOSTICS
ppp%d: af%d not supported . The interface was handed a message with addresses formatted in an unsuitable address family; the packet was
dropped.

The Point-to-Point Protocol (PPP), RFC 1661, July 1994.
HISTORY
The ppp device appeared in NetBSD 1.0.
BUGS
Currently, only the ip(4) and ip6(4) protocols are supported.
