Example: Configuring IS-IS for CLNS

This example shows how to create a routing instance and enable IS-IS protocol on all interfaces.


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


The configuration instructions in this topic describe how to create a routing-instance called aaaa, enable IS-IS on all interfaces, and define BGP export policy name (dist-bgp), family (ISO), and protocol (BP), and apply the export policy to IS-IS.



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 IS-IS for CLNS:

  1. Configure the routing instance.

  2. Enable CLNS routing.

  3. Enable IS-IS on all interfaces.

  4. (Optional) Disable IPv4 and IPv6 routing to configure a pure CLNS network .

  5. Define the BGP export policy name, family, and protocol.

  6. Define the action for the export policy.

  7. Apply the export policy to IS-IS.


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.


Confirm that the configuration is working properly.

Verifying Routing-Instance for CLNS


Verify that the policy options are enabled for the routing instance.


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

Verifying IS-IS for CLNS


Verify that IS-IS is enabled.


From operational mode, enter the show protocols command.
