The following MulticastServices have additional relationships in the Multicast
Manager repository:
Rendezvous points
The MulticastServices that are RPs have a
ServesAsRP relationship to each MulticastGroup that it supports. This is shown in
the following figure.

Designated routers
Multicast services that have the role of DR are the entry or exit points to the
multicast distribution tree. When a DR MulticastService is acting as the entry point

When a DR MulticastService is acting as the exit point from a multicast tree, each
IGMPNetwork object that represents a network that has one or more receivers in it
will have a relationship, ReportsToService, to it. This is shown in the following
