User Guidelines
In MLD snooping, when the IPv6 multicast router receives an MLD leave message,
it sends out queries to hosts belonging to the multicast group. If there are no
responses from a port to a MASQ for a length of time, the router deletes the port
from the membership database of the multicast address. The last listener query
interval is the maximum time that the router waits before deleting a nonresponsive
port from the multicast group. When a VLAN query interval is set, this interval
overrides the global query interval. When the VLAN interval is set at 0, the global
value is used.
Example
switchxxxxxx(config)#
ipv6 mld snooping vlan 3 last-member-query-interval 30
ipv6 mld snooping vlan mrouter learn pim-dvmrp
To enable automatic learning of multicast router ports on the switch or on a VLAN,
use the ipv6 mld snooping vlan mrouter learn pim-dvmrp Global Configuration
mode command.
To disable this feature on the VLANs, use the no form of this command.
