325 Configuring MLD SSM mappings By performing this configuration multiple times, you can map an IPv6 multicast group to different IPv6 multicast sources. If MLDv2 is enabled on a VLAN interface of a switch , and if a port in that VLAN is configured as a simulated host, the simulated host will send MLDv2 repo rts even if you did not specify an IPv6 multicast source when you configure simulated joining with the mld-snooping host-join c o m m a n d. I n t h i s c a s e, t h e corresponding IPv6 multicast group will not be created based on the configured MLD SSM mappings. For more information about the mld-snooping host-join command, see IP Multicast Command Reference . To configure an MLD SSM mapping: Step Command Remarks 1. Enter system view. system-view N/A 2. Enter MLD view. mld N/A 3. Configure an MLD SSM mapping. ssm-mapping ipv6-group-address prefix-length ipv6-source-address No MLD mappings are configured by default. Configuring MLD proxying Configuration prerequisites Before you configure the MLD proxying feature, complete the following tasks: • Enable IPv6 forwarding and configure an IPv6 unic ast routing protocol so that all devices in the domain are interoperable at the network layer. • Enable IPv6 multicast routing. Enabling MLD proxying You can enable MLD proxying on the interface in the direction toward the root of the multicast forwarding tree to make the device serve as an MLD proxy. Configuration guidelines • Each device can have only one interface serving as the MLD proxy interface. • You cannot enable MLD on interfaces with MLD proxying enabled. Moreover, only the mld require-router-alert , mld send-router-alert , and mld version commands can take effect on such interfaces. • You cannot enable other IPv6 multicast routing protocols (such as IPv6 PIM-DM or IPv6 PIM-SM) on interfaces with MLD proxying enabled, or vice versa. However, the source-lifetime, source-policy , and ssm-policy commands configured in IPv6 PIM view can still take effect. • You cannot enable MLD proxying on a VL AN inter face with MLD snooping enabled, or vice versa. Configuration procedure To enable MLD proxying:

Configuring IPv6 multicast forwarding on a downstream
interface
Typically, to avoid duplicate multicast flows, only queriers can forward IPv6 multicast traffic. On MLD
proxy devices, a downstream interface must be a querier in order to forward IPv6 multicast traffic to
downstream hosts. If the interface has failed in the querier election, you must manually enable IPv6
multicast forwarding on this interface.
IMPORTANT:
On a multi-access network with more than one MLD proxy devices, you cannot enable IPv6 multicast
forwarding on any other non-querier downstream inte
rface after one of the downstream interfaces of
these MLD proxy devices has been elected as the querier. Otherwise, duplicate multicast flows mi
ght be
received on the multi-access network.

MLD configuration examples
Basic MLD functions configuration example
Network requirements
As shown in Figure 87 , 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 Switch A and N1. MLDv1 runs be tween the other two switches (Switch B and Switch
C) and N2. Switch 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.

Enable IPv6 forwarding and configure IPv6 addresses and IPv6 unicast routing: Enable IPv6 forwarding on each switch and conf igure an IP address and prefix length for each interface as shown in Figure 87. (Details not shown.) Conf igure OSPFv3 for interoperation between the switches. Ensure the network-layer interoperation among the switch es on the IPv6 PIM network and dynamic update of routing information between the switches through a unic ast routing protocol.

Switch D’s VLAN-interface 104 serves as the C-BSR and C-RP. The SSM group range is FF3E::/64. MLDv2 runs on Switch D’s VLAN-interface 400. The receiver host runs MLDv1, and does not support MLDv2. Therefore, the Receiver host cannot specify expected multicast sources in its membership reports.

As shown in Figure 89, 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.
