3. Configure P2P network type for an
interface.

By default, the network type of an
interface depends on the physical
media. The network type of a
VLAN interface is broadcast.
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, Table 6 applies.
Configure the expected bandwidth of an interface with the bandwidth command. For more
information, see Interface Command Reference.

If none of the above costs is used, a default cost of 10 applies.
