Configuring source IPv6 addresses for MLD messages
Changing the source IPv6 address of MLD queries might affect MLD querier election within the
subnet.
To configure the source IP address for MLD queries in a VLAN:
Step Command Remarks
1. Enter system view.
system-view
N/A
2. Enter VLAN view.
vlan
vlan-id
N/A
3. Configure the source IPv6
address for MLD general
queries.
mld-snooping general-query
source-ip
ipv6-address
The default setting 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.
4. Configure the source IPv6
address for MLD
multicast-address-specific
queries.
mld-snooping special-query
source-ip
ipv6-address
By default, the source IPv6
address of MLD
multicast-address-specific
queries is one of the following:
• The source address of MLD
general queries if the MLD
snooping querier has
received MLD general
queries.
• The IPv6 link-local address
of the current VLAN interface
if the MLD snooping querier
does not receive an MLD
general query.
• FE80::02FF:FFFF:FE00:000
1 if the MLD snooping
querier does not receive an
MLD general query and the
current VLAN interface does
not have an IPv6 link-local
address.
5. Configure the source IPv6
address for MLD reports.
mld-snooping report source-ip
ipv6-address
The default setting 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.
6. Configure the source IPv6
address for MLD done
messages.
mld-snooping done source-ip
ipv6-address
The default setting 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.
