Globally configuring IS-IS on a device
2. If you have not already configured a NET for IS-IS, enter commands such as the following.
Brocade(config-isis-router)# net 49.2211.0000.00bb.cccc.00
Brocade(config-isis-router)#
The commands in the example above configure a NET that has the area ID 49.2211, the
system ID 0000.00bb.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 Brocade device’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 Brocade device.
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.
3. Configure IS-IS parameters. Refer to the sections “Globally configuring IS-IS on a device” on
page 255, “Configuring IPv4 address family route parameters” on page 267, and “Configuring
ISIS properties on an interface” on page 285.
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:
• Change the default metric.
• Add, change, or negate route redistribution parameters.
Some IS-IS parameter changes take effect immediately while others do not take full effect until you
disable, then re-enable route redistribution.
Globally configuring IS-IS on a device
This section describes how to change the global IS-IS parameters. These parameter settings apply
to both IS-IS IPv4 and IS-IS IPv6.
