Product Overview

The Edge Router Module (router module) is a serial port-to-token ring LAN interconnect module jointly developed by 3Com Corporation and Cisco Systems, Inc.

This section provides information on the following topics:

❑ Router Module Operation ❑ Router Module Architecture

Introduction 1 - 1

Router Module Operation

The router module (Figure 1-1) is designed to:

❑ Connect corporate networks and increase wide area connectivity . ❑ Support both synchronous and asynchronous routing over serial links

using one local area network (LAN) and up to three wide area network (WAN) connectio n s .

❑ Provide flexible networking connections in multiprotocol

environments.

❑ Sit at the network’s logical and physical edge, either at a remote site

or central facility.

Token Ring LAN

The router module runs Cisco standard software and fully interoperates with the:

❑ 3Com ONline Ethernet Router Module ❑ Cisco local and remote router servers, such as the AGS+, MGS ,

and the Cisco 3000, 4000, 4500, and 7000 series.

Router Module Archi tecture

Each router module consists of two compo nents:

❑ Engine Module - Provides Token Ring-to-WAN port connections. ❑ Carrier Module - Provides connections to one of three 3Com

switching hub products.

The engine mounts to one of three carrier types to form an Edge Router Module for th e ONline, ONsemble



, or ONcore hub products.

The architecture of each Edge Router Module type is illustrated in Figure 1-2.

Router Module Features

This section describes the major features of the router module , including:

❑ Softwa re O ptions ❑ Topology Switching Capability ❑ Network Reliability ❑ IOS Router Software Updates ❑ Memory Upgrades

Software Options

The router module provides a choice of four software feature sets:

❑ IP/IPX ❑ Desktop ❑ Desktop plus IBM ❑ Enterprise

Introduction 1 - 5

Feature

Topology Switching Capability

The router module provides to pology switching capability. Topology switching is the ability to switch the router module between token rin g networks (rings) on the hub backplane using:

❑ Network management module commands ❑ Simple Network Manag ement Protocol (SNMP)

You do not have to swap cables or move the router module to move the routing or brid ging function s to a different network within the hub. You can enter a command throu gh one of the 3Com management modules and the network change is made automatically.

Network Reliability

The router module provides the capability to implement several levels of reliability in your network:

❑ By configuring the router module’s WAN and auxiliary ports in

parallel, you can create up to three redundant serial links to protect your mission-critical applications.

❑ You can config ure up to two backup links to ensure that your

applications are available if the primary link fails.

An example of the router module configured to provide reliability is shown in Figure 1-3. These serial links can also support load-balancing to augment the performance of y our network.

IOS Router Software Updates

The IOS software in the router module engine can be updated by purchasing field-upgradable software distribution kits. Update your module to the latest 3Com release of IOS software by downloading new code to flash memory on the module. New updates are shipped automatically as part of the 3Com 1-year Router Software Subscription Service or you can purchase it from 3Com as a single unit update.

You can also purchase an upgrade kit to upgrade your IP/IPX, Desktop, or Desktop plus IBM

Contact your 3Com reseller or 3Com Customer Support for more information and part numbers.

Memory Upgrades

The router module provides the capability to increase memory to meet the requirements of large routing table configurations.

Memory is configured on the router module to match the requirements of the selected IOS software feature set. Table 1-2 lists the base memory configurations for each softw are feature set.
