Network requirements
As shown in Figure 85, the receivers receive VOD information in the multicast mode. The receivers of
different organizations form stub networks N1 and N2. Host A and Host C are multicast receivers in N1
and N2, respectively.
MLDv1 runs between Router A and N1. MLDv1 runs between the other two routers (Router B and Router
C) and N2. Router B acts as the MLD querier because it has a lower IPv6 address.
The hosts in N1 can only join IPv6 multicast group FF1E::101, and the hosts in N2 can join any IPv6
multicast groups.
