Configuring IPv4 IS-IS

Enabling IS-IS globally

To configure IPv4 IS-IS, do the following.
1. Globally enable IS-IS by entering the following command.
2. If you have not already configured a NET for IS-IS, enter commands such as the following.
3. Configure ISIS parameters. Refer to
None of the IS-IS parameters require a software reload to places changes into effect and most
parameter changes take effect immediately. However, changes for the following parameters take
effect only after you disable and then re-enable redistribution:
BigIron RX Series Configuration Guide
53-1002253-01
BigIron RX(config)# router isis
ISIS: Please configure NET!
Once you enter router isis, the device enters the IS-IS router configuration level.
Syntax: [no] router isis
To disable IS-IS, use the no form of this command.
BigIron RX(config-isis-router)# net 49.2211.aaaa.bbbb.cccc.00
BigIron RX(config-isis-router)#
The commands in the example above configure a NET that has the area ID 49.2211, the
system ID aaaa.bbbb.cccc (the device's base MAC address), and SEL value 00.
Syntax: [no] net <area-id>.<system-id>.<sel>
The <area-id> parameter specifies the area and has the format xx or xx.xxxx. For example, 49
and 49.2211 are valid area IDs.
The <system-id> parameter specifies the router's unique IS-IS router ID and has the format
xxxx.xxxx.xxxx. You can specify any value for the system ID. A common practice is to use the
device's base MAC address as the system ID. The base MAC address is also the MAC address
of port 1. To determine the base MAC address, enter the following command at any level of the
CLI: show interfaces brief. The base MAC address is listed in the first row of information, in the
MAC column.
You must use the same system ID in all the NETs on the BigIron RX
NOTE
The parameter descriptions above are the recommended values for the NET. However, the CLI
accepts any value that fits within the following lengths and formats.
xx.xxxx.xxxx.xxxx.00 – minimum length of NET
xx.xxxx.xxxx.xxxx.xxxx.xxxx.xxxx.xxxx.xxxx.xxxx.00 – maximum length of NET
The <sel> parameter specifies the NSAP Selector (SEL). This value must always be 00 (two
zeros). The value 00 indicates that this address is an NET.
To delete a NET, use the no form of this command.
