7.10.3 Enabling Multi-Topology for IPv4 IS-IS Interfaces

After enabling multi-topology for IS-IS, you need to associate a specified interface with an IS-
IS topology instance.
Context
An IS-IS interface can be associated with different topology instances, and the parameters of
this IS-IS interface can vary with the topology instances. The commands for configuring the
parameters are as follows:

Command that cancels the association between an IS-IS interface and an IPv4 base topology
Command that suppresses IS-IS to advertise direct routes of an interface in a specified
topology
Command that configures the cost of an interface in a specified topology instance
Command that disables an interface from participating in LFA calculation so that the
interface will not be a backup interface
Command that sets an administrative tag for an interface in a specified topology instance
