Chapter 11. 8260 Multiprotocol Interconnect Module

This chapter provides an overview of the routing and bridging functions provided by the Multiprotocol Interconnect module as well as discussing the steps required to configure the module to perform these functions.

In this document, we have assumed that the reader is familiar with routing and bridging protocols.

11.1 Introduction

The 8260 Multiprotocol Interconnect module is a one or two-slot module for the 8260 which allows you to interconnect Ethernet, 802.3, and token-ring networks using bridging and/or routing functions. These modules provide 6 ports for backplane attachments to the Ethernet segments on the ShuntBus or TriChannel. Additionally, the two-slot module provides you with the capability to install two additional I/O cards for providing connection to external token-ring and/or Ethernet networks. These additional I/O cards will provide the seventh and eighth port on the module. At the time of writing this book, the following I/O cards are available:

Token-ring 4/16 I/O card

Ethernet 10Base-T I/O card

Ethernet 10Base-2 I/O card

Ethernet 10Base-5 I/O card

Note that the I/O cards for the two-slot module only provide attachment capability to the external networks. For example, installation of the token-ring I/O card does not provide the ability to connect the module to the token-ring segments on the backplane.

The one-slot module can perform the following functions:

Transparent bridging between Ethernet/802.3 segments

IP routing between Ethernet/802.3 segments

IPX routing between Ethernet/802.3 segments

DECnet Phase IV routing between Ethernet/802.3 segments

The two-slot module can perform the following functions:

Transparent bridging between Ethernet/802.3 segments

Transparent bridging between token-ring segments operating at 4 and/or 16 Mbps

Source route transparent bridging between token-ring segments operating at 4 and/or 16 Mbps

Translational bridging between token-ring and Ethernet or 802.3 segments when both sides use transparent bridging

IP routing between Ethernet/802.3 and/or token-ring segments

IPX routing between Ethernet/802.3 and/or token-ring segments

DECnet Phase IV routing between Ethernet/802.3 segments
