Example: Configuring a JCS 1200 Platform and Multiple T-series Routers

In this configuration example, the JCS 1200 platform is connected to multiple T-series routing platforms. The configuration is described in the following sections:

• Requirements
• Overview
• Configuration
• Verification

Requirements

This configuration example requires the following hardware and software components:

• JUNOS Release 9.2 or later
• JCS 1200 platform with Routing Engines in slots 1 through 12
• T320 router with FPCs in slots 0 through 7
• T640 routing node with FPCs in slots 0 through 7
• T1600 routing node with FPCs in slots 0 through 7

Overview

This example configures the JCS 1200 platform and three connected T-series routing platforms. For this example, you need to configure a Root System Domain (RSD) for each connected T-series routing platform. Within each RSD, create Protected System Domains (PSDs) and assign Flexible PIC Controllers (FPCs) and Routing Engines to each PSD.

Configuration

First, configure the Routing Engines on the JCS 1200 platform using the management module CLI. Then, configure each T-series routing platform using the JUNOS CLI.

• T320 Router Configuration
• T640 Routing Node Configuration
• T1600 Routing Node Configuration

JCS 1200 Platform Configuration

Step-by-Step Procedure

To configure the parameters required for the Routing Engines in the JCS chassis:

1. Log into the JCS management module.
2. Refer to the data presented in Table 20 for Routing Engine assignments.

   Table 20: JCS Chassis Routing Engine Assignments

   RSD ID	PSD ID	Primary Routing Engine	Backup Routing Engine	Routing Platform
   1	1 2	01 03	02 04	T320
   2	3 4	05 07	06 08	T640
   3	5 6	09 11	10 12	T1600

3. Assign the Routing Engines in slots 1 (primary) and 2 (backup) to RSD1 and PSD1, which are associated with the T320 router. Assign the Routing Engines in slots 3 (primary) and 4 (backup) to RSD1 and PSD2, which also belongs to the T320 router.

Verifying Configured PSDs

Purpose

Verify that the PSDs configured under each RSD are online.

Action

Issue the show chassis psd command:

PSD  Description         State               Uptime
 1   psd for customer1   Online              1 hour, 12 minutes, 15 seconds

PSD  Description         State               Uptime
 3   psd for customer3   Online              1 hour, 12 minutes, 15 seconds
 4   psd for customer4   Online              1 hour, 12 minutes, 15 seconds

PSD  Description         State               Uptime

 6   psd for customer6   Online              1 hour, 12 minutes, 15 seconds

Meaning

RSD1 owns PSD1 and PSD2. RSD2 owns PSD3 and PSD4. RSD3 owns PSD4 and PSD5. All PSDs are online.

Verifying PSD Ownership of FPCs

Purpose

Verify that each PSD is assigned the correct FPCs on the T-series routing platform.

Action

For each PSD, issue the show chassis fpc command. For example:

rsd-re0:
--------------------------------------------------------------------------
                     Temp  CPU Utilization (%)   Memory    Utilization (%)
Slot State            (C)  Total  Interrupt      DRAM (MB) Heap     Buffer

Meaning

In this example, PSD1 owns the FPCs in slots 0, 1, 2, and 3 on the T-series routing platform.

Verifying PSD Ownership of Routing Engines

Purpose

Verify that each PSD owns the correct Routing Engines on the JCS chassis.

Action

On each PSD, issue the show chassis routing-engine command. For example:
