23 IPv6 MLD Snooping Querier Commands IGMP/MLD Snooping Querier is an extension of the IGMP/MLD Snooping feature. IGMP/MLD Snooping Querier allows the switch to simulate an IGMP/MLD router in a Layer 2-only network, thus removing the need to have an IGMP/MLD Router to collect the multicast group membership information. The querier function simulates a small subset of the IGMP/MLD router functionality. In a network with IP multicast routing, the IP multicast router acts as the IGMP/MLD querier. However, if it is required that the IP-multicast traffic in a VLAN be switched, the switch can be configured as an IGMP/MLD querier. When IGMP/MLD Snooping Querier is enabled, the Querier sends out periodic IGMP/MLD General Queries that trigger the Multicast listeners/member to send their joins so as to receive the Multicast data traffic. IGMP/MLD Snooping listens to these reports to establish the appropriate forwarding table entries. PowerConnect switches support IGMP V1 and 2 for snooping IGMP queries. Commands in this Chapter This chapter explains the following commands: ipv6 mld snooping querier ipv6 mld snooping querier query-interval ipv6 mld snooping querier (VLAN mode) ipv6 mld snooping querier timer expiry ipv6 mld snooping querier address show ipv6 mld snooping querier ipv6 mld snooping querier election participate IPv6 MLD Snooping Querier Commands 499
