Step
1. Enter system view.
2. Enter interface view.
3. Configure P2P network type for an
interface.

Configuring IS-IS route control

Configuration prerequisites

Before the configuration, complete the following tasks:
Configure IP addresses for interfaces to ensure IP connectivity between neighboring nodes.
•
• Enable IS-IS.

Configuring IS-IS link cost

The IS-IS cost of an interface is determined in the following order:
1. IS-IS cost specified in interface view.
2. IS-IS cost specified in system view.
The cost is applied to the interfaces associated with the IS-IS process.
3. Automatically calculated cost.
If the cost style is wide or wide-compatible, IS-IS automatically calculates the cost using the formula:
Interface cost = (Bandwidth reference value / Expected interface bandwidth) × 10, in the range of
1 to 16777214. For other cost styles,
Configure the expected bandwidth of an interface with the bandwidth command. For more
information, see Interface Command Reference.
Table 6 Automatic cost calculation scheme for cost styles other than wide and wide-compatible
Interface bandwidth
≤ 10 Mbps
≤ 100 Mbps
≤ 155 Mbps
≤ 622 Mbps
≤ 2500 Mbps
> 2500 Mbps
If none of the above costs is used, a default cost of 10 applies.

By default, the network type of an
interface depends on the physical
media. The network type of a
VLAN interface is broadcast.
