Example: Configuring IS-IS for CLNS
This example shows how to create a routing instance and enable IS-IS protocol on all interfaces.
Requirements
Before you begin, configure the network interfaces. See Interfaces User Guide for Security Devices.
Overview
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.
Configuration
Procedure
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.
set routing-instances aaaa protocols isis clns-routing set routing-instances aaaa protocols isis interface all set routing-instances aaaa protocols isis no-ipv4-routing no-ipv6-routing set policy-options policy-statement dist-bgp from family iso protocol bgp set policy-options policy-statement dist-bgp then accept set routing-instances aaaa protocols isis export dist-bgp
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:
Configure the routing instance.
[edit] user@host# edit routing-instances aaaa
Enable CLNS routing.
[edit routing-instances aaaa] user@host# set protocols isis clns-routing
Enable IS-IS on all interfaces.
[edit routing-instances aaaa] user@host# set protocols isis interface all
(Optional) Disable IPv4 and IPv6 routing to configure a pure CLNS network .
[edit routing-instances aaaa] user@host# set protocols isis no-ipv4-routing no-ipv6-routing
Define the BGP export policy name, family, and protocol.
[edit policy-options] user@host# set policy-statement dist-bgp from family iso protocol bgp
Define the action for the export policy.
[edit policy-options] user@host# set policy-statement dist-bgp then accept
Apply the export policy to IS-IS.
[edit routing-instances aaaa] user@host# set protocols isis export dist-bgp
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.
[edit]
user@host# show routing-instances
aaaa {
protocols {
isis {
export dist-bgp;
no-ipv4-routing;
no-ipv6-routing;
clns-routing;
interface all;
}
If you are done configuring the device, enter commit from configuration mode.
Verification
Confirm that the configuration is working properly.
Verifying Routing-Instance for CLNS
Purpose
Verify that the policy options are enabled for the routing instance.
Action
From operational mode, enter the show routing-instances command.
