that want to receive the data, instead of being flooded to all ports in a VLAN. This list is constructed by snooping IPv6 multicast control packets.

MLD is a protocol used by IPv6 multicast routers to discover the presence of multicast listeners (nodes configured to receive IPv6 multicast packets) on its directly attached links and to discover which multicast packets are of interest to neighboring nodes. MLD is derived from IGMP; MLD version 1 (MLDv1) is equivalent to IGMPv2, and MLD version 2 (MLDv2) is equivalent to IGMPv3. MLD is a subprotocol of Internet Control Message Protocol version 6 (ICMPv6), and MLD messages are a subset of ICMPv6 messages, identified in IPv6 packets by a preceding Next Header value of 58.

The switch can snoop on both MLDv1 and MLDv2 protocol packets and bridge IPv6 multicast data based on destination IPv6 multicast MAC addresses. The switch can be configured to perform MLD snooping and IGMP snooping simultaneously.

CLI: Configure MLD Snooping

1.Enter the following commands.

(Netgear Switch) #vlan da (Netgear Switch) (Vlan)#vlan 300 (Netgear Switch) (Vlan)#exit (Netgear Switch) #config

(Netgear Switch) (Config)#interface 1/0/1

(Netgear Switch) (Interface 1/0/1)#vlan participation include 300 (Netgear Switch) (Interface 1/0/1)#vlan pvid 300

(Netgear Switch) (Interface 1/0/1)#exit (Netgear Switch) (Config)#interface 1/0/24

(Netgear Switch) (Interface 1/0/24)#vlan participation include 300 (Netgear Switch) (Interface 1/0/24)#vlan pvid 300

(Netgear Switch) (Interface 1/0/24)#exit (Netgear Switch) (Config)#exit (Netgear Switch) (Config)#set mld (Netgear Switch) (Config)#exit (Netgear Switch) #vlan database (Netgear Switch) (Vlan)#set mld 300 (Netgear Switch) (Vlan)#exit

2.Enable MLD snooping on VLAN 300.

(Netgear Switch) #show mldsnooping
Admin Mode	Enable
Multicast Control Frame Count	0
Interfaces Enabled for MLD Snooping	None
VLANs enabled for MLD snooping	300
