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:  

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. 

 

Before configuring an MLD snooping policy, complete the following tasks:  

z 

Enable MLD snooping in the VLAN  

Before configuring an MLD snooping policy, prepare the following data:  

z 

IPv6 ACL rule for IPv6 multicast group filtering  

z 

The maximum number of IPv6 multicast groups that can pass the ports  

z 

802.1p precedence for MLD messages 

On a MLD snooping–enabled switch, the configuration of an IPv6 multicast group filter allows the 

service provider to define limits of multicast programs available to different users.  

In an actual application, when a user requests a multicast program, the user’s host initiates an MLD 

report. Upon receiving this report message, the switch checks the report against the configured ACL 

rule. If the port on which the report was received can join this IPv6 multicast group, the switch adds an 

entry for this port in the MLD snooping forwarding table; otherwise the switch drops this report message. 

Any IPv6 multicast data that fails the ACL check will not be sent to this port. In this way, the service 

provider can control the VOD programs provided for multicast users.  

Follow these steps to configure an IPv6 multicast group globally:  

Enter system view

Enter MLD snooping view
