Operation Manual – Multicast ProtocolH3C S3610&S5510 Series Ethernet Switches Chapter 8 Multicast Policy Configuration8-68.3.4 Configuring a Multicast Route Match PolicyIn RPF route selection, the device chooses an optimal route from the multicast staticrouting table and from the unicast routing table respectively, and then chooses thebetter route from these two routes. The route match policy falls in two cases:z In the case of route selection based on the longest match principle,1) The router choose the longest-match route from the two routes;2) If these two routes have the same mask, the route with a higher priority will bechosen;3) If these two routes have the same priority, the route selection will be based thesequence of multicast static route – unicast route.z If route selection is not based on the longest match principle,4) The route with a higher priority will be chosen;5) If these two routes have the same priority, the route selection will be based thesequence of multicast static route – unicast route.Follow these steps to configure multicast a route match policy:To do...

The multicast data correspondingto each multicast group must be transmitted within a definite scope. Presently, you candefine a multicast forwarding range by:
