Chapter 38 Configuring IPv6 MLD Snooping
Configuring IPv6 MLD Snooping
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):
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.

The range is 100 to 32,768 thousands of a second. The default is 1000
(1 second).

last-listener-query-interval interval
(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.

Step 8
ipv6 mld snooping tcn query solicit
(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.
