MLD proxying configuration example
Network requirements
As shown in Figure 91 , IPv6 PIM-DM is required to run 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.
Figure 91 Network diagram for MLD proxying configuration
Configuration procedure
1. Enable IPv6 forwarding and configure the IPv6 addresses
Enable IPv6 forwarding on each switch and configure the IPv6 address and prefix length of each
interface as per Figure 91 . (details not shown)
2. Enable IPv6 multicast routing, IPv6 PIM-DM, MLD, and MLD proxying respectively.
# Enable IPv6 multicast routing on Switch A, IPv6 PIM-DM on VLAN-interface 101, and MLD on
VLAN-interface 100.
