Enabling MLD snooping proxying
The MLD snooping proxying function works on a per-VLAN basis. After you enable the function in a
VLAN, the device works as the MLD snooping proxy for the downstream hosts and upstream router in the
VLAN.
Follow these steps to enable MLD snooping proxying in a VLAN:
To do... Use the command... Remarks
Enter system view system-view —
Enter VLAN view vlan vlan-id —
Enable MLD snooping proxying
in the VLAN
mld-snooping proxying enable
Required
Disabled by default.
Configuring a source IPv6 address for the MLD messages sent
by the proxy
You can set the source IPv6 addresses in the MLD reports and done messages sent by the MLD snooping
proxy on behalf of its attached hosts.
Follow these steps to configure the source IPv6 addresses for the MLD messages sent by the MLD
snooping proxy on behalf of its attached hosts in a VLAN:
To do... Use the command... Remarks
Enter system view system-view —
Enter VLAN view vlan vlan-id —
Configure a source
IPv6 address for the
MLD reports sent by the
proxy
mld-snooping report source-ip
{ ipv6-address | current-interface }
Required
The default is
FE80::02FF:FFFF:FE00:0001.
Configure a source
IPv6 address for the
MLD done messages
sent by the proxy
mld-snooping done source-ip
{ ipv6-address | current-interface } The default is
FE80::02FF:FFFF:FE00:0001.
Configuring an MLD snooping policy
Configuration prerequisites
Before you configure an MLD snooping policy, complete the following tasks:
• Enable MLD snooping in the VLAN
• Determine the IPv6 ACL rule for IPv6 multicast group filtering
• Determine the maximum number of IPv6 multicast groups that can pass the ports
• Determine the 802.1p precedence for MLD messages
