By default, the level of an interface is level-1-2.
NOTE
Changing the level of an IS-IS interface is valid only when the level of the IS-IS device is
Level-1-2. If the level of the IS-IS device is not a Level-1-2, the level of the IS-IS device
determines the level of the adjacency to be established.
l (Optional) Suppress an IS-IS interface.
1. Run:
system-view
The system view is displayed.
2. Run:
interface interface-type interface-number
The interface view is displayed.
3. Run:
isis silent
The IS-IS interface is suppressed.
A suppressed IS-IS interface does not send or receive IS-IS packets. The routes of the
network segment where the interface resides, however, can still be advertised to other
routers within the area.

6.3.4 (Optional) Configuring the IPv4 IS-IS Interfaces
Configuring the IS-IS interface costs can control IS-IS route selection.
Context
The costs of IS-IS interfaces can be determined in the following modes in descending order by
priority:
l Interface cost: is configured for a specified interface.
l Global cost: is configured for all interfaces.
l Automatically calculated cost: is automatically calculated based on the interface
bandwidth.
If none of the preceding configurations is performed, the default cost of an IS-IS interface is 10,
and the default cost style is narrow.
Procedure
l Configure the IS-IS cost type.
1. Run:
system-view
The system view is displayed.
2. Run:
isis [ process-id ]
The IS-IS view is displayed.
