Example: Configuring a VPN Routing Instance for CLNS

 

This example shows how to create a CLNS routing instance and set the instance type for Layer 3 VPNs.

Requirements

Before you begin, configure the network interfaces. See Interfaces User Guide for Security Devices.

Overview

The following example shows how to create a CLNS routing instance called aaaa and set the instance type to VRF for Layer 3 VPNs. Within the example, you specify that the lo0.1 interface, e1–2/0/0.0 interface, and t1–3/0/0.0 interface all belong to the routing instance. The route distinguisher is set as 10.255.245.1:1 and the policy for the Layer 3 VRF table is set as target:11111:1.

Configuration

CLI Quick Configuration

To quickly configure this example, copy the following commands, paste them into a text file, remove any line breaks, change any details necessary to match your network configuration, copy and paste the commands into the CLI at the [edit] hierarchy level, and then enter commit from configuration mode.

Step-by-Step Procedure

The following example requires you to navigate various levels in the configuration hierarchy. For instructions on how to do that, see Using the CLI Editor in Configuration Mode.

To configure a VPN routing instance:

  1. Create the routing instance.
  2. Specify the routing instance type.
  3. Specify the interfaces that belong to the routing instance.
  4. Specify the route distinguisher.
  5. Specify the policy for the Layer 3 VRF table.
  6. Enable family ISO on the interfaces edit interfaces interface-name unit-id.

Results

From configuration mode, confirm your configuration by entering the show routing-instances command. If the output does not display the intended configuration, repeat the configuration instructions in this example to correct it.

If you are done configuring the device, enter commit from configuration mode.

Verification

Verifying the Configured CLNS Routing Instance

Purpose

Confirm that the configuration is working properly.

Verify that the CLNS routing instance is configured.

Action

From operational mode, enter the show routing-instances command.
