Chapter 25 Configuring IPv6 MLD Snooping
Command
Step 6
ipv6 mld snooping
last-listener-query-interval interval
Step 7 ipv6 mld snooping vlan vlan-id
last-listener-query-interval interval
Step 8 ipv6 mld snooping tcn query solicit
Step 9
ipv6 mld snooping tcn flood query count
count
Step 10
end
Step 11 show ipv6 mld snooping querier [vlan
vlan-id]
Step 12 copy running-config startup-config
This example shows how to set the MLD snooping global robustness variable to 3:
Switch# configure terminal
Switch(config)# ipv6 mld snooping robustness-variable 3
Switch(config)# exit
This example shows how to set the MLD snooping last-listener query count for a VLAN to 3:
Switch# configure terminal
Switch(config)# ipv6 mld snooping vlan 200 last-listener-query-count 3
Switch(config)# exit
This example shows how to set the MLD snooping last-listener query interval (maximum response time)
to 2000 (2 seconds):
Switch# configure terminal
Switch(config)# ipv6 mld snooping last-listener-query-interval 2000
Switch(config)# exit

Disabling MLD Listener Message Suppression

MLD snooping listener message suppression is enabled by default. When it is enabled, the switch
forwards only one MLD report per multicast router query. When message suppression is disabled,
multiple MLD reports could be forwarded to the multicast routers.
OL-13270-06
Purpose
(Optional) Set the maximum response time that the switch waits after
sending out a MASQ before deleting a port from the multicast group.
The range is 100 to 32,768 thousands of a second. The default is 1000
(1 second).
(Optional) Set the last-listener query interval on a VLAN basis. This
value overrides the value configured globally. The range is 0 to 32,768
thousands of a second. The default is 0. When set to 0, the global
last-listener query interval is used.
(Optional) Enable topology change notification (TCN) solicitation,
which means that VLANs flood all IPv6 multicast traffic for the
configured number of queries before sending multicast data to only
those ports requesting to receive it. The default is for TCN to be
disabled.
(Optional) When TCN is enabled, specify the number of TCN queries
to be sent. The range is from 1 to 10; the default is 2.
Return to privileged EXEC mode.
(Optional) Verify that the MLD snooping querier information for the
switch or for the VLAN.
(Optional) Save your entries in the configuration file.
