3. Configure the network type for the
interface as P2P.
isis circuit-type p2p
Optional.
By default, the network type
of an interface depends on
the physical media.
NOTE:
You can only perform this configuration for a broadcast network with only two attached routers.
Configuring IS-IS routing information control
Configuration prerequisites
Before the configuration, complete the following tasks:
• Configure network layer addresses for interfaces, and make sure that all neighboring nodes can
reach each other at the network layer.
• Enable IS-IS.
Configuring IS-IS link cost
The IS-IS cost of an interface is determined in the following order:
• IS-IS cost specified in interface view
• IS-IS cost specified in system view. The cost is applied to the interfaces associated to the IS-IS
process.
• Automatically calculated cost. When the cost style is wide or wide-compatible, IS-IS automatically
calculates the cost using the formula: interface cost = (bandwidth reference value/interface
bandwidth) ×10. When the cost style is of another type: if the interface bandwidth does not exceed
10 Mbps, the interface cost equals 60; if the interface bandwidth does not exceed 100 Mbps, the
interface cost equals 50; if the interface bandwidth does not exceed 155 Mbps, the interface cost
equals 40; if the interface bandwidth does not exceed 622 Mbps, the interface cost equals 30; if
the interface bandwidth does not exceed 2500 Mbps, the interface cost equals 20; if the interface
bandwidth exceeds 2500 Mbps, the interface cost equals 10.
If none of the above costs is used, a default cost of 10 applies.
