Configuring source IPv6 addresses for MLD messages
About configuring source IPv6 addresses for MLD messages
You can change the source IPv6 address of the MLD queries sent by an MLD snooping querier. This configuration might affect MLD querier election within the subnet.
You can also change the source IPv6 address of MLD reports or done messages sent by a simulated member host or an MLD snooping proxy.
Configuring the source IPv6 addresses for MLD messages for a VLAN

vlan vlan-id
Configure the source IPv6 address for MLD general queries.
mld-snooping general-query source-ip ipv6-address
By default, the source IPv6 address of MLD general queries 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.
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 of the VLAN 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:FE00:0001 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.
Configure the source IPv6 address for MLD reports.
mld-snooping report source-ip ipv6-address
By default, the source IPv6 address of MLD reports 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.
Configure the source IPv6 address for MLD done messages.
mld-snooping done source-ip ipv6-address
By default, the source IPv6 address of MLD done messages 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.

Configure the source IPv6 address for MLD general queries.
mld-snooping general-query source-ip ipv6-address
By default, the source IPv6 address of MLD general queries is the IPv6 link-local address of the gateway interface for a VSI. If the gateway interface does not have an IPv6 link-local address, the source IPv6 address is FE80::02FF:FFFF:FE00:0001.
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 of the VSI has received MLD general queries.
IPv6 link-local address of the gateway interface for the VSI if the MLD snooping querier does not receive an MLD general query.
FE80::02FF:FFFF:FE00:0001 if the gateway interface does not have an IPv6 link-local address.
Configure the source IPv6 address for MLD reports.
mld-snooping report source-ip ipv6-address
By default, the source IPv6 address of MLD reports is the IPv6 link-local address of the gateway interface for a VSI. If the gateway interface does not have an IPv6 link-local address, the source IPv6 address is FE80::02FF:FFFF:FE00:0001.
Configure the source IPv6 address for MLD done messages.
mld-snooping done source-ip ipv6-address
By default, the source IPv6 address of MLD done messages is the IPv6 link-local address of the gateway interface for a VSI. If the gateway interface does not have an IPv6 link-local address, the source IPv6 address is FE80::02FF:FFFF:FE00:0001.
