Abstract
The Point-to-Point Protocol (PPP) [1] 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 NCP for establishing and configuring
Digital's DNA Phase IV Routing protocol (DECnet Phase IV) over PPP.
This document applies only to DNA Phase IV Routing messages (both
data and control), and not to other DNA Phase IV protocols (MOP, LAT,
etc.).
1. Introduction
There are two basic approaches to running the DNA Phase IV Routing
protocol over a serial line:
1. The approached that several router vendors have taken which is to
treat the serial link as an Ethernet, using the same data and
control messages an Ethernet would use.
2. The approach defined by Digital, which uses DDCMP and slightly
different control messages.
This document will define a method that uses the first approach.
