• Enable MLD snooping in the VLAN. • Determine the aging time of dynamic router ports. • Determine the aging time of dynamic member ports. • Determine the IPv6 multicast group and IPv6 multicast source addresses. Configuring aging timers for dynamic ports If a switch receives no MLD general queries or IPv6 PIM hello messages on a dynamic router port when the aging timer of the port expires, the switch removes the port from the router port list. If the switch receives no MLD reports for an IPv6 multicast group on a dynamic member port when the aging timer of the port expires, the switch removes the port from the forwarding entry for the IPv6 multicast group. If the memberships of IPv6 multicast groups change frequently, you can set a relatively small value for the aging timer of the dynamic member ports. If the memberships of IPv6 multicast groups change rarely, you can set a relatively large value. Setting the global aging timers for dynamic ports Step Command 1. Enter system view. system-view 2. Enter MLD-snooping view. mld-snooping 3. Set the global aging timer for dynamic router ports. router-aging-time interval 4. Set the global aging timer for dynamic member ports. host-aging-time interval Setting the aging timers for the dynamic ports in a VLAN Remarks N/A N/A 260 seconds by default 260 seconds by default Step 1. Enter system view. 2. Enter VLAN view. 3. Set the aging timer for the dynamic router ports. 4. Set the aging timer for the dynamic member ports. Command system-view vlan vlan-id mld-snooping router-aging-time interval mld-snooping host-aging-time interval Remarks N/A N/A 260 seconds by default 260 seconds by default Configuring static ports If all hosts attached to a port are interested in the IPv6 multicast data addressed to a particular IPv6 multicast group, configure the port as a static member port for that IPv6 multicast group. You can configure a port as a static router port, through which the switch can forward all IPv6 multicast data that it received. 214
