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.

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.

2. Overview Of Phase IV DNA Protocols

The Phase IV DNA protocols which act as data link clients are:

o DNA Phase IV Routing

The Phase IV Digital Network Architecture (DNA) Routing

protocol is a network layer protocol providing services similar

to that of DoD IP. It routes messages in Phase IV DECnet

networks and manages the packet flow. The complete definition

of the DNA Phase IV Routing protocol can be found in [2].

o DNA System Console

The Digital Network Architecture (DNA) System Console protocol

is a maintenance protocol providing low level access to a

system for the functions of:

. Identify processor

. Read data link counters

. Boot system

. Console carrier (a general purpose i/o channel)

The complete definition of the DNA System Console protocol can

be found in [3].

o Digital Customer Use

The Digital Customer Use protocol type is a value reserved for

use by Digital customers. It allocates a type for private use

which will not conflict with Digital or other vendor protocols.

o DNA Diagnostics

The Digital Network Architecture (DNA) Diagnostics protocol

type is reserved to allow ...
