When configuring a multicast static route, you cannot specify an RPF neighbor by providing the type
and number (interface-type interface-number) of the interface connecting the RPF neighbor if the
interface type of the RPF neighbor is Ethernet, Layer 3 aggregate, Loopback, RPR, or VLAN-interface;
instead, you can specify such an RPF neighbor only by its address (rpf-nbr-address).
Configuring a Multicast Routing Policy
You can configure the router to determine the RPF route based on the longest match principle. For
details about RPF route selection, refer to
By configuring per-source or per-source-and-group load splitting, you can optimize the traffic delivery
when multiple data flows are handled.
