Usage guidelines
This command and the source-deny command in MLD-snooping view have the same function but
different effective ranges:
• The source-deny command in MLD-snooping view takes effect on the specified ports.
• The mld-snooping source-deny command takes effect on the current port.
For a port, the mld-snooping source-deny command and the source-deny command in MLD-snooping
view have the same priority, and the most recent configuration takes effect.
Examples
# Enable source port filtering for IPv6 multicast data on Ten-GigabitEthernet 1/0/1.
<Sysname> system-view
[Sysname] interface ten-gigabitethernet 1/0/1
[Sysname-Ten-GigabitEthernet1/0/1] mld-snooping source-deny

mld-snooping special-query source-ip
Use mld-snooping special-query source-ip to configure a source IPv6 address for MLD
multicast-address-specific queries.
Use undo mld-snooping special-query source-ip to restore the default.
Syntax
mld-snooping special-query source-ip ipv6-address
undo mld-snooping special-query source-ip
Default
If the MLD snooping querier has received MLD general queries, the source IP address of MLD
multicast-address-specific queries is the IPv6 address of the MLD general queries. Otherwise, the source
IP address is the IPv6 link-local address of the current VLAN interface. If the current VLAN interface does
not have an IPv6 link-local address, the source IPv6 address is FE80::02FF:FFFF:FE00:0001.
Views
VLAN view
Predefined user roles
network-admin
Parameters
ipv6-address: Specifies a source IPv6 address for MLD multicast-address-specific queries.
Usage guidelines
You must enable MLD snooping for a VLAN before you execute this command for the VLAN.
Examples
# In VLAN 2, enable MLD snooping, and configure FE80:0:0:1::1 as the source IPv6 address of MLD
multicast-address-specific queries.
<Sysname> system-view
[Sysname] mld-snooping
