Usage guidelines
IS-IS processes not enabled with the multi-instance process feature are called traditional IS-IS
processes. IS-IS processes enabled with the multi-instance process feature are called IS-IS
multi-instance processes.
By default, an interface supports only one IS-IS process. To configure multiple IS-IS processes on a
device, you must add more interfaces to the device and configure the interfaces manually. To
simplify configuration, use the IS-IS multi-instance process feature to configure multiple IS-IS
multi-instance processes as well as a traditional IS-IS process on an interface.
After you enable the IS-IS multi-instance process feature, two devices can establish a neighbor
relationship only when you configure the same instance ID for the multi-instance processes on the
devices.
When you configure IS-IS multi-instance processes or disable the IS-IS multi-instance process
feature, follow these restrictions and guidelines:
•
You cannot specify the same instance ID for different IS-IS processes.
•
Before enabling or disabling the IS-IS multi-instance process feature on an interface that has
been configured with an IS-IS process, disable IS-IS on the interface.
