Configuring Layer 2 Multicast MLD Snooping Configuration Step 9 ipv6 mld snooping vlan-config vlan-id-list querier (Optional) Enable MLD Snooping Querier for the VLAN. By default, it is disabled. When enabled, the switch acts as an MLD Snooping Querier for the hosts in this VLAN. A querier periodically sends a general query on the network to solicit membership information, and sends group-specific queries when it receives done messages from hosts. vlan-id-list: Specify the ID or the ID list of the VLAN(s). Note: To enable MLD Snooping Querier for a VLAN, MLD Snooping should be enabled both globally and in the VLAN. After enabling MLD Snooping Querier feature, you need to specify the corresponding parameters including the Last Member Query Count, Last Member Query Interval, Maximum Response Time, Query Interval and General Query Source IP. Use the command below in global configuration mode to configure the parameters: ipv6 mld snooping vlan-config vlan-id-list querier { max-response-time response-time | query-interval interval | general-query source-ip ip-addr | last-listener-query-count num | last-listener-query-interval interval } vlan-id-list: Specify the ID or the ID list of the VLAN(s). response-time: Specify the host's maximum response time to general query messages. query-interval interval: Specify the interval between general query messages sent by the switch. ip-addr: Specify the source IP address of the general query messages sent by the switch. It should be a unicast address. num: Specify the number of group-specific queries to be sent. With MLD Snooping Querier enabled, when the switch receives a done message, it obtains the address of the multicast group that the host wants to leave from the message. Then the switch sends out MASQs to this multicast group through the port receiving the done message. If specified count of MASQs are sent and no report message is received, the switch will delete the multicast address from the multicast forwarding table. last-listener-query-interval interval: Specify the interval between MASQs. Step 10 show ipv6 mld snooping vlan vlan-id Show the basic MLD snooping configuration in the specified VLAN. Step 11 end Return to privileged EXEC mode. Step 12 copy running-config startup-config Save the settings in the configuration file. The following example shows how to enable MLD Snooping for VLAN 1, and configure the member port aging time as 300 seconds, the router port aging time as 320 seconds, and then enable Fast Leave and Report Suppression for the VLAN: Switch#configure Switch(config)#ipv6 mld snooping vlan-config 1 mtime 300 User Guide 240
