Figure 36. IGMP Version 3–Capable Multicast Routers Address Structure
Joining and Filtering Groups and Sources
The following illustration shows how multicast routers maintain the group and source information from unsolicited reports.
1 The rst unsolicited report from the host indicates that it wants to receive trac for group 224.1.1.1.
2 The host’s second report indicates that it is only interested in trac from group 224.1.1.1, source 10.11.1.1. Include messages prevents
trac from all other sources in the group from reaching the subnet. Before recording this request, the querier sends a group-and-
source query to verify that there are no hosts interested in any other sources. The multicast router must satisfy all hosts if they have
conicting requests. For example, if another host on the subnet is interested in trac from 10.11.1.3, the router cannot record the
include request. There are no other interested hosts, so the request is recorded. At this point, the multicast routing protocol prunes
the tree to all but the specied sources.
3 The host’s third message indicates that it is only interested in trac from sources 10.11.1.1 and 10.11.1.2. Because this request again
prevents all other sources from reaching the subnet, the router sends another group-and-source query so that it can satisfy all other
hosts. There are no other interested hosts so the request is recorded.
