Configure the port-based multicast VLAN feature on Switch A so that Router A just sends multicast data 
to Switch A through the multicast VLAN and Switch A forwards the multicast data to the receivers that 
belong to different user VLANs.

Configuring multicast routing and forwarding 
(available only on the HP 5500 EI) 
Overview 
In multicast implementations, the following types of tables implement multicast routing and forwarding: 
•  Multicast routing table of a multicast routing protocol —Each multicast routing protocol has its own 
multicast routing table, such as PIM routing table. 
•   General multicast routing table —The multicast routing information of different multicast routing 
protocols forms a general multicast routing...

The router chooses an optimal route from the unic ast routing table, the MBGP routing table, and 
the static multicast routing table:  
{  The router automatically chooses an optimal unicast route by searching its unicast routing table, 
and using the IP address of the packet source as the destination address. The outgoing 
interface in the corresponding routing entry is  the RPF interface and the next hop is the RPF 
neighbor. The router considers the path along which the packet from the RPF...

If the corresponding (S, G) entry exists, but th e interface that received the packet is not the 
incoming interface in the multicast forwarding table, the multicast packet undergoes an RPF check.   
{  If the RPF interface is the incoming interface of the (S, G) entry, it indicates that the (S, G) entry 
is correct but the packet arrived from a wrong path. The packet will be discarded.  
{ If the RPF interface is not the incoming interface, it indicates that the (S, G) entry has expired, 
and...
