DIGITAL GIGAswitch/IP Solution for ATM

This document serves as an installation and configuration guide for network administrators managing DIGITAL GIGAswitch/IP and IP Switch Gateway products in ATM environments. It outlines the process of designing a network, including IP addressing, subnetting, and the selection of routing protocols such as OSPF, RIP, and DVMRP, with a recommendation for 30-bit masks on ATM point-to-point links.

The guide details the four main steps of installation: network design, physical hardware installation, software upgrades, and configuration verification. It provides instructions for upgrading preloaded software and configuring the network using either the ASCII-based Lynx browser or the graphical clearVISN IP Switch Manager (Netscape Navigator). Step-by-step procedures cover interface configuration, file generation, and applying changes to the system. Verification involves checking system synchronization, interface status, remote addresses, neighbor reachability, and unicast routing tables using commands like ifconfig and netstat. The document also includes information on backing up and restoring configuration files.

An extensive troubleshooting section addresses common problems such as synchronization failures between components, unconfigured interfaces, lack of IFMP synchronization, issues with pinging neighbors, traceroute difficulties, and problems with IP switching networks learning routes from RIP-attached routers. Supporting appendices provide network design tables and detailed subnet mask reference charts.
