MLD proxying configuration example
Network requirements
As shown in Figure 99 , IPv6 PIM-DM runs on the core network. Host A and Host C in the stub network
receive VOD information destined to multicast group FF3E::101.
Configure the MLD proxying feature on Switch B so that Switch B can maintain group memberships and
forward IPv6 multicast traffic without running IPv6 PIM-DM.
