DECnet Overview

This chapter shows how Nortel Networks router software works with DECnet

services and describes the following:

• Organization of end nodes and routers in a DECnet network

• Transmission of messages from the Nortel Networks router through the

DECnet network

• Routing decision process for a DECnet network

• DECnet IV to V Transition feature

• Purpose of static routes

• Static adjacency support

DECnet Network Organization

A DECnet network contains two types of nodes: end nodes and routers. End nodes

send and receive messages. Routers transmit messages to end nodes and other

routers on the network.

DECnet Phase IV Organization

DECnet Phase IV is a networking protocol that supports large networks (up to

approximately 64,000 nodes). You can divide each network into as many as 63

distinct areas; each area contains up to 1023 nodes. You must assign to each area

an Area ID, unique to the network. You must also assign to each node within an

area a Node ID, unique to the area.
