To prevent loops, routers do not forward multicast out the
same interface on which they were received. Multicast routers use a reverse path
forwarding (RPF) check to prevent loops. A multicast router does not forward
any multicast packet unless the packet passes the RPF check..
 |
| The RPF check compares incoming packets with the unicast routing table to determine if a packet is arriving on the correct interface. |
The issue of receiving duplicate packets, Cisco
routers perform a reverse path forwarding (RPF)
Check to determine whether a multicast packet is entering a
router on the correct interface
An RPF check examines the source address of an incoming
packet and check it against the router’s uni-cast routing table to see what
interface should be used to get back to the source network. If the incoming multicast packet is using that interface,
the RPF check passes, and the packet is forwarded.
If the multicast packet is coming in a different interface,
the RPF check fails, and packet is discarded.
