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 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 The maximum number of IPv6 multicast groups that can pass the ports
z 802.1p precedence for MLD messages
Configuring Dropping Unknown IPv6 Multicast Data
Unknown IPv6 multicast data refers to IPv6 multicast data for which no forwarding entries exist in the
MLD snooping forwarding table: When the switch receives such IPv6 multicast traffic:
z With the function of dropping unknown IPv6 multicast data enabled, the switch drops all unknown
IPv6 multicast data received.
z With the function of dropping unknown IPv6 multicast data disabled, the switch floods unknown
IPv6 multicast data in the VLAN to which the unknown IPv6 multicast data belongs.
Follow these steps to enable dropping unknown IPv6 multicast data globally:
To do... Use the command... Remarks
Enter system view system-view —
Enter MLD snooping view mld-snooping —
Enable dropping unknown IPv6
multicast data
drop-unknown
Required
Disabled by default
