Configuring IPv6 MLD snooping on a per-VLAN basis
The following IPv6 MLD snooping parameters can be configured on a per-VLAN basis:
• Active and passive - “Configuring IPv6 multicast snooping per VLAN”
• MLD proxy - “Configuring MLD proxy per VLAN”
• PIM-SM traffic snooping - “Configuring the PIM-SM traffic snooping per VLAN”
• PIM proxy - “Configuring PIM proxy per VLAN”
• Static-group uplink - “Configuring an IPv6 multicast static group uplink per VLAN”
• Tracking - “Configuring IPv6 multicast tracking and fast-leave per VLAN”
Configuring IPv6 multicast snooping per VLAN
The multicast6 command allows you to configure IPv6 multicast snooping parameters per VLAN. To
configure IPv6 multicast snooping to VLAN 2, enter the following commands as shown in the
example below.
Brocade(config)# vlan 2
Brocade(config-vlan-2)# multicast6 active
To remove multicast traffic reduction configurations in VLAN 2, and take the global multicast traffic
reduction configuration, enter the following command. Do not enter the active or passive keywords
when removing the multicast traffic reduction configuration.
Brocade(config)# vlan 2
Brocade(config-vlan-2)# no multicast6
Syntax: [no] multicast6 active | passive
When you enable IPv6 multicast for a specific VLAN, MLD snooping is enabled. The device uses
MLD to maintain a table of the Group Membership reports received by the device for the specified
VLAN. You can use active or passive MLD mode. There is no default mode.
The description for the MLD modes is as follows:
• Active – When active MLD mode is enabled, the router actively sends out MLD queries to
identify IPv6 multicast groups within the VLAN and makes entries in the MLD table based on
the Group Membership reports received from the network.
• Passive – When passive MLD mode is enabled, the router listens for MLD Group Membership
reports on the VLAN specified but does not send MLD queries. The passive mode is called
“MLD snooping”. Use this mode when another device in the VLAN is actively sending queries.
Configuring MLD proxy per VLAN
The multicast6 mld-proxy-enable command enables MLD proxy for IPv6. Using the MLD proxy
function, the host is able send out MLD reports on behalf of the hosts behind the switch.
To configure a device to function as an MLD proxy on VLAN 2, enter the following commands as
shown in this example.
Brocade(config)# vlan 2
Brocade(config-vlan-2)# multicast6 active
Brocade(config-vlan-2)# multicast6 mld-proxy-enable
Syntax: [no] multicast6 mld-proxy-enable
The no form of this command disables MLD proxy on a per-VLAN basis.
