Global Area
The Global area of the C6576M IS-IS dialog box provides the following information:
• CLNS Enabled—Indicates whether or not CLNS routing is enabled on the device. CLNS routing
must be enabled for the IS-IS routing process to function. If CLNS routing is disabled, some
attributes of the IS-IS object may not be accessible.
IS-IS Area
The IS-IS area of the C6576M IS-IS dialog box provides the following information:
• Area Tag—IS-IS routing process area tag. Mandatory if configuring multiarea IS-IS; otherwise, it
is optional. If no tag is specified, the default null tag is assumed.
• Level—Describes whether the routing process performs Layer 1, Layer 1 and Layer 2, or Layer 2
only routing. By default, the first IS-IS routing process created on a device is set to perform Layer 1
and Layer 2 routing; any other processes created will by default be configured to perform Layer 1
routing only.
Note There may be, at most, one process on the device performing Layer 2 routing; this process can also
perform Layer 1 routing. There may be up to 29 additional routing processes performing Layer 1 only
routing.
Configuring IS-IS Area
The Configuring IS-IS area allows you to create an IS-IS routing process on the managed device and
deploy an instance of the IS-IS object in the element manager.
• New Area Tag—IS-IS routing process area tag. Mandatory if configuring multiarea IS-IS;
otherwise, it is optional. If no tag is specified, the default null tag is assumed.
