Multicast Properties

Forwarding Rules and Querier
The following rules are applied:
• A Multicast packet received on the upstream interface is forwarded on all downstream interfaces
requesting the packet only if the proxy device is the querier on the interfaces.
• A proxy device drops Multicast packets received on a downstream interface if it is not the querier on
the interface.
• A Multicast packet received on a downstream interface on which the proxy device is the querier is
forwarded on the upstream interface and on all downstream interfaces requesting the packet only if
the proxy device is the querier on the interfaces.
Downstream Interface Protection
By default, IP Multicast traffic arriving on an interface of the IGMP/MLD tree is forwarded. You can disable of
IP Multicast traffic forwarding arriving on downstream interfaces. It can be done globally and on a given
downstream interface.
