7.18.3 Enabling Multi-Topology for IPv6 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:
l
Command that cancels the association between an IS-IS interface and an IPv6 base topology
l
Command that suppresses IS-IS to advertise direct routes of an interface in a specified
topology
l
Command that configures the cost of an interface in a specified topology instance
