IPv6 multicast group and IPv6 multicast source addresses
■
If the switch receives no MLD general queries or IPv6 PIM hello messages on a
dynamic router port, the switch removes the port from the router port list when
the aging timer of the port expires.
If the switch receives no MLD reports for an IPv6 multicast group on a dynamic
member port, the switch removes the port from the outgoing port list of the
forwarding table entry for that IPv6 multicast group when the aging timer of the
port for that group expires.
If IPv6 multicast group memberships change frequently, you can set a relatively
small value for the member port aging timer, and vice versa.
Configuring aging timers for dynamic ports globally
Follow these steps to configure aging timers for dynamic ports globally:
To do...
Enter system view
Enter MLD Snooping view
Configure router port aging

Configure member port aging

Configuring aging timers for dynamic ports in a VLAN
Follow these steps to configure aging timers for dynamic ports in a VLAN:
To do...
Enter system view
Enter VLAN view
Configure router port
aging time
Configure member port
aging time
If all the hosts attached to a port is interested in the IPv6 multicast data addressed
to a particular IPv6 multicast group, you can configure that port as a static
member port for that IPv6 multicast group.
You can configure a port of a switch to be static router port, through which the
switch can forward all IPv6 multicast data it received.
Follow these steps to configure static ports:
To do...
Enter system view
Use the command...
system-view
mld-snooping
router-aging-time interval
host-aging-time interval
Use the command...
system-view
vlan vlan-id
