Groups - Cal Amp Dataradio HiPR-900 User Manual

In an HiPR-900 environment, an outside host (Sender) might be interested in sending multicast packets to
any one of the following groups:
•
"All Remote HiPR-900" group.
•
Various "Remote Host" group.
The main HiPR-900 unit is directly connected to the outside network. ALL multicast groups MUST be
identified in the main HiPR-900 unit because it uses IGMP to register the memberships to the multicast
groups on behalf of the other units and Hosts (Remote HiPR-900 units, Remote Hosts).
