Introduction

This document provides configuration information for how to connect two BPX 8600 switches with narrowband trunks. Each BPX 8600 switch has an MGX 8220 Edge Concentrator connected as a feeder shelf. The customer premises equipment (CPE) is connected to the feeder shelf. A four T1 inverse multiplexing over ATM (IMA) trunk group is established between two MGX 8220 IMATM-8T3T1/B service modules. A T3 trunk is established between each BPX 8600 BXM-T3 service module and the respective MGX8220 IMATM-8T3T1/B. Two Cisco multichannel (MC) 3810 routers with Frame Relay interfaces are connected to each of the MGX 8220 Frame Relay Service Modules (FRSM)-8T1. IP connectivity between two Cisco MC 3810 routers is achieved through a network interworking (NIW) connection. The MGX 8220 FRSM-8T1 service modules provide the NIW conversion. BPX 8600 switches provide the switching function for this connection.

Note: This document is designed to help you configure Cisco equipment. It is not a substitute for proper network design and planning that you can achieve with your Cisco sales engineer, systems engineer, or account manager.

Prerequisites

Requirements

There are no specific requirements for this document.

Components Used

The information in this document is based on these software and hardware versions:

  • BPX 8600 switches

  • MGX 8220 Edge Concentrators

  • MC 3810 routers

  • MGX 8220 IMATM/B cards

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

Conventions

Refer to the Cisco Technical Tips Conventions for more information on document conventions.

Versions

The versions used in this document are based on generally available releases and are not intended as strict requirements. Read the applicable release notes in order to verify that required interfaces and configurations are supported on each of the platforms.

  • MC 3810

    Software—Cisco IOS® Software Release 12.0(3) and 12.0(4)T

    Hardware—Cisco MC 3810 with T1 multiflex trunk (MFT) interface

  • MGX 8220

    Both Cisco MGX 8220 Edge Concentrators use the same Cisco firmware release and hardware configuration.

    Firmware—Cisco release 5.0.14 and the appropriate versions of service module hardware and firmware on both MGX 822s.

    Hardware—A Cisco IMATM model B service module is used for ATM Forum compliant IMA. Four T1 trunks are used between the two IMATM 8T3T1/B service modules on each of the MGX 8220 Edge Concentrators. The IMATM/B service modules use RJ48 connectors for T1 lines and a coaxial connector for the T3 line. The T3 port on each of the IMATM 8T3T1/B service modules is connected to the respective BXM-T3 port on the BPX 8600 switches. The FRSM-8T1 service module uses RJ48 connectors and connects to the respective MC 3810 MFT interface.

  • BPX 8600

    Both BPX 8600 switches use the same Cisco switch software version.

    Software—Cisco Switch Software Release 9.1.18 and the appropriate versions of card hardware and firmware as specified in the Release Notes.

    Hardware—The BPX 8600 switch is connected to the MGX 8220 feeder shelf with a Broadband Network Interface (BNI)-T3 card set. The BXM-T3 card set connects to the MGX 8220 IMATM/B service module. The BXM-T3 service module uses service message block (SMB) connectors. The BNI-T3 service module uses coaxial connectors.

Configurations

This document uses these configurations:

Note: Make all physical connections before you create configurations.

MGX 8220 IMATM-8T3T1/B - New York

Add the lines on the IMATM-8T3T1/B card to be included in the inverse multiplexing over ATM (IMA) group.

mgx8220a.1.8.IMATMB.a > addln 1  
mgx8220a.1.8.IMATMB.a > addln 2  
mgx8220a.1.8.IMATMB.a > addln 3  
mgx8220a.1.8.IMATMB.a > addln 4

Check all lines and clear alarms before you add lines to the IMA group. It is recommended that you use contiguous lines in an IMA group. However, it is not required. An IMA group can be composed of lines 1, 3, 4, and 5.

Note: Line framing and line coding for the T1s between the two IMATM/B service modules must match.

1 minimum no of links—minimum number of links for the group formation;value ranges from 1 to 8. This number must be the same at each end of the IMA group.

Add a channel route for the IMA group with the addchrte command. This command creates a virtual path identifier (VPI) map listing on the IMATM and defines which cells are routed to which IMA group. If a single IMA group is defined and the VPI range being sent from the attached equipment (here, the BPX 8600) is not known, then specify the entire VPI range.

4095 Max. VPI value—0-255 (UNI/VpTrkUNI), 0-1023(STI), 0-4095(NNI). In this case, the port type is NNI so the max. value of 4095 is used.

Verify that the IMATM-8T3T1/B port payload scrambling configuration is the same at both ends of the IMA trunk. Payload scrambling was developed in order to ensure that the ATM cell payload does not resemble a cell header. It is significant only locally. Specifically, each side of an ATM interface must have the same payload scrambling value, but all ATM interfaces in the network do not require the same configuration.

MGX 8220 IMATM-8T3T1/B - Jakarta

The configuration for the MGX 8220 IMATM/B service module is identical to the MGX 8220 IMATM/B for New York. Repeat the steps listed for this configuration in order to configure the IMATM/B.

MGX 8220 FRSM - Jakarta

The configuration for the MGX 8220 FRSM service module is identical to the MGX 8220 FRSM for New York. Repeat the steps listed in this configuration in order to configure the FRSM.

BPX 8600 - Jakarta

Add the MGX 8220 as a feeder shelf to the BPX 8600 switch. Activate the BXM-T3 trunk, as mentioned in this document, for the BPX 8600 in New York. Also, configure the Transmit Rate for a BXM-T3 trunk in order to match the other end of the trunk.

Add the trunk between the nodes with the addtrk command. This command is executed at one of the nodes that terminates the trunk. A trunk must be free of major alarms before you can add it.
