Chapter 6 Template 62
IGMP filter templates allow you to control access to IGMP multicast groups. This allows you
to have a service available to a specific IGMP multicast group. You can configure an IGMP
filter template for an IGMP multicast group that has access to a service (like a SIP server for
example).
6.3.1 IP Multicast Addresses
In IPv4, a multicast address allows a device to send packets to a specific group of hosts
(multicast group) in a different subnetwork. A multicast IP address represents a traffic
receiving group, not individual receiving devices. IP addresses in the Class D range (224.0.0.0
to 239.255.255.255) are used for IP multicasting. Certain IP multicast numbers are reserved by
IANA for special purposes (see the IANA web site for more information).
