Multicast multi-topology in IS-IS uses a topology dedicated to route calculation for multicast services to guide multicast traffic forwarding.

Multicast multi-topology is IS-IS is applicable in the following situations:
The multicast and unicast topologies need to use different routing policies to prevent them from affecting each other.

A TE tunnel exists in the unicast topology. The multicast service and TE tunnel service cannot be deployed together; therefore, multicast multi-topology is required to isolate the multicast service and TE tunnel service.
