Configuring IS-IS

Step-by-Step Procedure

The following example requires you to navigate various levels in the configuration hierarchy. For information about navigating the CLI, see Using the CLI Editor in Configuration Mode in the CLI User Guide.

To configure IS-IS:

1. Enable IS-IS if your router is in secure context.
   [edit security forwarding-options family iso]user@R1# set mode packet-based
2. Create the interface that connects to Device R2, and configure the ISO family on the interface.
   [edit interfaces ge-1/2/0 unit 0]user@R1# set description to-R2user@R1# set family inet address 10.0.0.1/30user@R1# set family iso
3. Create the loopback interface, set the IP address, and set the NET address.
   [edit interfaces lo0 unit 0]user@R1# set family inet address 192.168.0.1/32user@R1# set family iso address 49.0002.0192.0168.0001.00
4. Enable IS-IS on the interfaces.
   [edit protocols isis]user@R1# set interface ge-1/2/0.0user@R1# set interface lo0.0

Results

From configuration mode, confirm your configuration by entering the show interfaces, show protocols, and show security commands. If the output does not display the intended configuration, repeat the instructions in this example to correct the configuration.

user@R1# show security

forwarding-options {family iso {mode packet-based;}}

user@R1# show interfaces

ge-1/2/0 {unit 0 {description to-R2;family inet {address 10.0.0.1/30;}family iso;}}

lo0 {unit 0 {family inet {address 192.168.0.1/32;}family iso {address 49.0002.0192.0168.0001.00;}}}

user@R1# show protocols

isis {interface ge-1/2/0.0;interface lo0.0;}

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