7.7.6 IPv4 and IPv6 SSM Information

Use the IPv4 SSM Information
Source Specific Multicast (SSM) is a datagram delivery model that best supports one-to-many applications, also known as broadcast applications. SSM
is a core network technology of IP multicast targeted for audio and video broadcast application environments.
For the SSM delivery mode, an IP multicast receiver host must use IGMPv3 or MLDv2 to subscribe to channel (S, G). By subscribing to this channel, the
receiver host is indicating that it wants to receive IP multicast traffic sent by source host S to group G. The network will deliver IP multicast packets from
source host S to group G to all hosts in the network that have subscribed to the channel (S, G).
SSM does not require group address allocation within the network, only within each source host. Different applications running on the same source host
must use different SSM groups. Different applications running on different source hosts can arbitrarily reuse SSM group addresses without causing any
excess traffic on the network.
IPv4 addresses in the range 232.0.0.0/8 (232.0.0.0 to 232.255.255.255) are reserved for SSM by IANA. In the switch, you can configure SSM for arbi-
trary IP multicast addresses also.
