Network requirements
As shown in Figure 398, receivers receive VOD information in the multicast mode. Receivers of different
organizations form stub networks N1 and N2, and Host A and Host C are multicast receivers in N1 and
N2 respectively.
MLDv1 runs between Firewall A and N1 and between the other two routers (Firewall B and Firewall C)
and N2. Firewall B acts as the MLD querier because it has a lower IPv6 address.
The hosts in N1 can join only IPv6 multicast group FF1E::101, and the hosts in N2 can join any IPv6
multicast groups.
