Example: Configuring the JCS1200 Platform as a Route Reflector

In this configuration example, a T640 router and four Routing Engines on the JCS1200 platform are configured for route reflection.

Requirements

This configuration example requires the following hardware and software components:

  • JUNOS Release 9.5 or later
  • One JCS1200 platform with Routing Engines in slots 1, 2, 3, and 4
  • One T640 router with FPCs in slots 0, 1, and 2

Overview and Topology

Figure 1: Example: Route Reflection

Image g017296.gif

Figure 1 shows a T640 router (T-route) and four Routing Engines (RR, R1, R2, and R3) on the JCS1200 chassis (bcg) configured for route reflection.

Each router is configured as a separate PSD. Each PSD has an associated Routing Engine assigned on the JCS chassis and an associated FPC assigned on the T640 router. Table 1 provides the chassis parameters required for the JCS1200 platform and for the T640 router for each PSD.

JCS1200 Configuration

Step-by-Step Procedure

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

  1. Log in to the JCS management module CLI.
  2. Configure the Routing Engine that is part of PSD15. This Routing Engine is located in slot 1 of the JCS chassis and acts as the route reflector.

    To configure the Routing Engine in slot 1, issue the following command:

    system> baydata —b 01 —data “V01–JCS1–SD2–PSD15–REP01–REB00–PRDSCE”

    The baydata command specifies the target as a bay blade (-b), identifies the Routing Engine (blade) in slot 01, and specifies the following parameters:

    • V01—Product version, which is 01.
    • JCS1—JCS platform identifier, which is 1.
    • SD2—RSD identifier, which is 2.
    • PSD15—PSD identifier, which is 15.
    • REP01—Slot in which the primary Routing Engine resides, which is 01.
    • REB00—Slot in which the backup Routing Engine resides. 00 indicates that there is no backup Routing Engine.
    • PRDSCE—Juniper Networks router product. There is a special product type for the route reflector: Standalone Control Element (SCE).
  3. Configure the Routing Engine that is part of PSD11 This Routing Engine is located in slot 2 of the JCS chassis and acts as standalone router (not a route reflector).

    To configure the Routing Engine in slot 2, issue the following command:

    system> baydata —b 02 —data “V01–JCS1–SD1–PSD11–REP02–REB00–PRDT640”

    The baydata command specifies the target as a bay blade (-b), identifies the blade (Routing Engine) in slot 02, and specifies the following parameters:

    • V01—Product version, which is 01.
    • JCS1—JCS platform identifier, which is 1.
    • SD1—RSD identifier, which is 1. This router is in SD1, the route reflector is in SD2.
    • PSD11—PSD identifier, which is 11.
    • REP02—Slot in which the primary Routing Engine resides, which is 02.
    • REB00–Slot in which the backup Routing Engine resides. 00 indicates that there is no backup Routing Engine.
    • PRDT640—Juniper Networks router product, which is the T640 router.
  4. Configure the Routing Engine that is part of PSD12. This Routing Engine is located in slot 3 of the JCS chassis and acts as standalone router (not a route reflector).

    To configure the Routing Engine in slot 3, issue the following command:

    system> baydata —b 03 —data “V01–JCS1–SD1–PSD12–REP03–REB00–PRDT640”

    The baydata command specifies the target as a bay blade (-b), identifies the blade (Routing Engine) in slot 02, and specifies the following parameters:

    • V01—Product version, which is 01.
    • JCS1—JCS platform identifier, which is 1.
    • SD1—RSD identifier, which is 1. This router is in SD1, the route reflector is in SD2.
    • PSD12—PSD identifier, which is 12.
    • REP03—Slot in which the primary Routing Engine resides, which is 03.
    • REB00–Slot in which the backup Routing Engine resides. 00 indicates that there is no backup Routing Engine.
    • PRDT640—Juniper Networks router product, which is the T640 router.
  5. Configure the Routing Engine that is part of PSD13. This Routing Engine is located in slot 4 of the JCS chassis and acts as standalone router (not a route reflector).

    To configure the Routing Engine in slot 4, issue the following command:

    system> baydata —b 04 —data “V01–JCS1–SD1–PSD13–REP04–REB00–PRDT640”

    The baydata command specifies the target as a bay blade (-b), identifies the blade (Routing Engine) in slot 02, and specifies the following parameters:

    • V01—Product version, which is 01.
    • JCS1—JCS platform identifier, which is 1.
    • SD1—RSD identifier, which is 1. This router is in SD1, the route reflector is in SD2.
    • PSD13—PSD identifier, which is 13.
    • REP04—Slot in which the primary Routing Engine resides, which is 04.
    • REB00–Slot in which the backup Routing Engine resides. 00 indicates that there is no backup Routing Engine.
    • PRDT640—Juniper Networks router product, which is the T640 router.

RSD Configuration

Step-by-Step Procedure

To configure the RSD:

  1. Log in to the T640 router.
  2. At the [edit chassis system-domains] hierarchy level of the JUNOS CLI, include the root-domain-id 1 statement to identify the RSD associated with Router 1, 2, and 3.
  3. At the [edit chassis system-domains] hierarchy level, include the protected-system-domains psd11 statement to create PSD11.
  4. At the [edit chassis system-domains protected-system-domains psd11] hierarchy level:
    1. Include the description “bcgcpu2 SWLab R1” statement to describe the PSD.
    2. Include the fpcs 1 statement to assign the FPC in slot 1 to PSD11.
    3. Include the control-system-id 1 statement to identify the JCS1200 platform.
    4. Include the control-slot-numbers 2 statement to assign the Routing Engine in slot 2 in the JCS chassis to PSD11.
  5. At the [edit chassis system-domains] hierarchy level, include the protected-system-domains psd12 statement to create PSD12.
  6. At the [edit chassis system-domains protected-system-domains psd12] hierarchy level:
    1. Include the description “bcgcpu3 SWLab R2” statement to describe the PSD.
    2. Include the fpcs 2 statement to assign the FPC in slot 2 to PSD12.
    3. Include the control-system-id 1 statement to identify the JCS1200 platform.
    4. Include the control-slot-numbers 3 statement to assign the Routing Engine in slot 3 in the JCS chassis to PSD12.
  7. At the [edit chassis system-domains] hierarchy level, include the protected-system-domains psd13 statement to create PSD13.
  8. At the [edit chassis system-domains protected-system-domains psd13] hierarchy level:
    1. Include the description “bcgcpu4 SWLab R3” statement to describe the PSD.
    2. Include the fpcs 0 statement to assign the FPC in slot 0 to PSD13.
    3. Include the control-system-id 1 statement to identify the JCS1200 platform.
    4. Include the control-slot-numbers 4 statement to assign the Routing Engine in slot 4 in the JCS chassis to PSD13.

Results

Display the results of the configuration:

chassis {
system-domains {
root-domain-id 1;
protected-system-domains {
psd11 {
description "bcgcpu2 SWLab R1";
fpcs 1;

}
psd13 {
description "bcgcpu4 SWLab R3";
fpcs 0;
control-system-id 1;
control-slot-numbers 4;
}
}
}
}

The RSD configuration on the T640 router does not include a root-domain-id 2 statement for domain 2 (the route reflector domain) or any protected-system-domains PSD15 statements for the route reflector PSD. This is because the route reflector is self-contained within the JCS chassis and does not require configuration on the T640 router.
