Using Multicast Filtering
Multicast filtering improves the performance of networks that carry multicast traffic. This section explains
multicasts, multicast filtering, and how multicast filtering can be implemented on your IKS-6726.
The Concept of Multicast Filtering
What is an IP Multicast?
A multicast is a packet sent by one host to multiple hosts. Only those hosts that belong to a specific multicast
group will receive the multicast. If the network is set up correctly, a multicast can only be sent to an end-station
or a subset of end-stations on a LAN or VLAN that belong to the multicast group. Multicast group members can
be distributed across multiple subnets, so that multicast transmissions can occur within a campus LAN or over
a WAN. In addition, networks that support IP multicast send only one copy of the desired information across the
network until the delivery path that reaches group members diverges. To make more efficient use of network
bandwidth, it is only at these points that multicast packets are duplicated and forwarded. A multicast packet
has a multicast group address in the destination address field of the packet’s IP header.
