In the E-DBA environment, an outside sender-host might be interested in sending multicast packets to
any one of the following groups:
“All Mobile” group.
Various “Mobile Host” groups.
The Base (P4 in the illustration) units are directly connected to the outside network. ALL multicast
groups MUST be identified in the Base because the Base unit uses IGMP to register the memberships to
the multicast groups on behalf of the other units (Mobile units, Mobile Host units).
