device selects a route as the multicast data forwarding path in the order of the static route, inter-
domain unicast route, and intra-domain unicast route.

CAUTION
Configurations related to VPN instances are applicable only to the PE switch. When configuring
the longest match of multicast routes for a VPN instance on a PE, perform the configuration in
the VPN instance. In other cases, the longest match is configured in the public network instance.
By default, routes are selected in the order of routing entries.
Do as follows on the multicast switch:
Procedure

9.4.3 Configuring Multicast Load Splitting
The multicast load splitting function extends multicast routing rules, which does not fully depend
on the RPF check. Performing load splitting of multicast traffic according to different policies
can optimize network traffic transmission in the scenario where multiple multicast data flows
exist. You can choose to configure a balance-preferred or stable-preferred load splitting policy.
