Preface

This manual contains the information that you will need to use the router userinterface for configuration and operation of the Multiprotocol Routing Services basecode installed on your Nways device. With the help of this manual, you should beable to perform the following processes and operations:

v Configure, monitor, and use the Multiprotocol Routing Services base code.v Configure, monitor, and use the interfaces and Link Layer software supported by

your Nways device .

This manual is the first volume of the software library for the 2210, which isdescribed in IBM 2210 Nways Multiprotocol Router Publications on page xxx. Aspecific Nways device might not support all of the features and functions describedwithin the library. If a feature or function is device-specific, that restriction isindicated in the relevant manual.

This manual refers to the 2210 as either the router or the device. The examplesin the library represent the configuration of a 2210, but the actual output you seemay vary. Use the examples as a guideline to what you might see while configuringyour device.

Who Should Read This ManualThis manual is intended for persons who install and manage computer networks.Although experience with computer networking hardware and software is helpful,you do not need programming experience to use the protocol software.

Getting Additional InformationChanges may be made to the documentation after the books are printed. Ifadditional information is available or if changes are required after the books havebeen printed, the changes will be in a file (named README) on the CD-ROM. Youcan view the file with an ASCII text editor.

About the SoftwareIBM Nways Multiprotocol Routing Services is the software that supports the IBM2210 (licensed program number 5801-ARR). This software has these components:

v The base code, which consists of: The code that provides the routing, bridging, data link switching, and SNMP

agent functions for the device.

The router user interface, which allows you to configure, monitor, and use theMultiprotocol Routing Services base code installed on the device. The routeruser interface is accessed locally through an ASCII terminal or emulatorattached to the service port, or remotely through a Telnet session ormodem-attached device.

The base code is installed at the factory on the 2210.

v The Configuration Program for IBM Nways Multiprotocol Routing Services(referred to in this book as the Configuration Program) is a graphical userinterface that enables you to configure the device from a stand-alone workstation.The Configuration Program includes error checking and online help information.

Copyright IBM Corp. 1994, 1999 xxix

The Configuration Program is not pre-loaded at the factory; it is shippedseparately from the device as part of the software order.

You can also obtain the Configuration Program for IBM Nways MultiprotocolRouting Services from the IBM Networking Technical Support home page. SeeConfiguration Program Users Guide for Nways Multiprotocol and AccessServices,, GC30-3830, for the server address and directories.

Conventions Used in This ManualThe following conventions are used in this manual to show command syntax andprogram responses:

1. The abbreviated form of a command is underlined as shown in the followingexample:reload

In this example, you can enter either the whole command (reload) or itsabbreviation (rel).

2. Keyword choices for a parameter are enclosed in brackets and separated by theword or. For example:

command [keyword1 or keyword2]

Choose one of the keywords as a value for the parameter.

3. Three periods following an option mean that you enter additional data (forexample, a variable) after the option. For example:time host ...

In this example, you enter the IP address of the host in place of the periods, asexplained in the description of the command.

4. In information displayed in response to a command, defaults for an option areenclosed in brackets immediately following the option. For example:Media (UTP/STP) [UTP]

In this example, the media defaults to UTP unless you specify STP.

5. Keyboard key combinations are indicated in text in the following ways:v Ctrl-Pv Ctrl -The key combination Ctrl - indicates that you should press the Ctrl key and thehyphen simultaneously. In certain circumstances, this key combination changesthe command line prompt.

6. Names of keyboard keys that you press are indicated like this: Enter

7. Variables (that is, names used to represent data that you define) are denoted byitalics. For example:File Name: filename.ext

IBM 2210 Nways Multiprotocol Router PublicationsLibrary reorganization: Beginning with Version 3.2, the following changes to theorganization of the library took place:

v The information in the Software Users Guide titled Understanding, Using andConfiguring Features was moved into a new manual, Using and ConfiguringFeatures.

xxx MRS V3.4 Software Users Guide

v The chapters on using, configuring, and monitoring the DIALs feature weremoved into the Using and Configuring Features book.

Summary of Changes for the IBM 2210 Software LibraryThe following list applies to the changes in the software that were made in Version3 Release 4:

v Frame Relay enhancements: New Frame Handler (FH) support PU throttling to handle bursts of traffic in support of 3745 controllers New interface type (Frame Relay subinterface) to allow virtual interfaces on

the same physical interface Unnumbered IP support

v VPN enhancements: CPE enhancements:

- Policy information from LDAP servers is locally stored.- Policy quick configuration.- Policy consistency checking.- Policy information may now be retrieved from LDAP servers within an

administrative domain.- IPSec tunnel ping.

IP enhancements:

- Voice routing enhancements:v IP Header Compression on PPP (RFCs 2507, 2508, 2509)

v Interleaving voice traffic between fragmented data packets on multi-linkPPP

v Interleaving voice traffic between fragmented data packets on FrameRelay

v Bypassing PPP or Frame Relay packet compression and encryption forvoice traffic

- IP loopback address

This support allows users to define IP addresses on a special interface tosupport TN3270 Gateway, Network Dispatcher, and IPSec requirements.

- IPv6

v An inter-domain routing function (BGP4+) is provided for IPv6 thatsupports IPv6 routing and addressing information and uses TCP6 fortransport.

v IPv6 traffic is supported over ATM ethernet LAN emulation withoutencapsulation or tunneling.

- Multiple forwarding paths

IP routing can use up to four equal-cost static routes to support multipleparallel links to a given address and mask.

- IP route aggregation

- Multicast enhancements:

v Protocol Independent Multicast-Dense Mode (PIM-DM) for IPv4.v Network administrators can now control the flow of IP multicast data into

and out of their networks by using inbound and outbound traffic filters.

- Not-so-stubby area (NSSA)

OSPF supports not-so-stubby area (NSSA) as defined in RFC 1587 andthe latest Internet draft is now supported.

- Random Early Detection (RED)

- Differential services policing enhancements

- VRRP enhancements:

v The hardware MAC address may be used instead of a virtual MACaddress to identify a redundant gateway; this can offer a performanceimprovement.

v When more than one backup candidate is available, preempt options canbe configured.

v For selecting the master IP router, additional criteria, such as availableroute or network interface, can be used to support non-IP functions.

v Dial-on-demand alternate interface for WAN reroutev TN3270 enhancements

LU capping LU-pool load balancing Talk 5 disconnect of TN3270 sessions Additional reporting information Support of addresses 1 and 255

v Network Dispatcher enhancements Advertising of network dispatcher cluster addresses by routing protocols A new SSL Advisor

v DLSw SDLC PU1 supportv Ethernet encapsulation support for both ethernet type II (default) and 802.3

simultaneously on the same interface

v DHCP enhancements:
