PPP Configuration Options
Since PPP includes the LCP protocol, the following LCP parameters can be controlled:
Authentication . RFC 1994 describes the Challenge Handshake Authentication Protocol ( CHAP ) which is the preferred way to perform PPP authentication, although the Password Authentication Protocol ( PAP ) is sometimes still used. Another option for authentication is the Extensible Authentication Protocol ( EAP ).
Compression . Effectively increases the throughput of a PPP connection by compressing data in a frame. The best known PPP frame compression algorithms are Stacker and Predictor.
Error detection . Includes Quality-Protocol and helps identify feedback loops through Magic Numbers RFC 1661 .
Multichannel . Multilink PPP (MLPPP, MPPP, MLP) provides methods for propagating traffic over multiple physical links with a single logical connection. This option allows you to expand bandwidth and provides load balancing.
