Configuring IS-IS Link
Cost
There are three ways to configure the interface link cost, in descending order of
interface costs:
Interface cost: Assign a link cost for a single interface.
■
Global cost: Assign a link cost for all interfaces.
■
Automatically calculated cost: Calculate the link cost based on the bandwidth
■
of an interface.
Interface cost defaults to 10.
