Enter the ssm-enable command under the IPv6 router PIM level to globally enable source specific
multicast filtering.
Setting the query interval
You can define the frequency at which MLD query messages are sent. For example, if you want
queries to be sent every 50 seconds, enter a command such as the following.
BigIron RX(config)#ipv6 mld query-interval 50
Syntax: ipv6 mld query-interval <seconds>
Specify 1 – 3600 for <seconds>. The default is 60 seconds.
Setting the maximum response time
You can define the maximum amount of time a multicast listener has to respond to queries by
entering a command such as the following.
BigIron RX(config)#ipv6 mld max-response-time 5
Syntax: ipv6 mld max-response-time <seconds>
Specify 1 – 64 for <seconds>. The default is 5 seconds.
Setting the last listener query count
The Last Listener Query Count is the number of Multicast-Address- Specific Queries sent before the
switch assumes there are no remaining listeners for an address on a link. You can set the last
listener query count by entering a command such as the following.
BigIron RX(config)#ipv6 mld llqc 5
Syntax: ipv6 mld llqc <seconds>
Specify 2 – 7 for <seconds>.
Setting the last listener query interval
The Last Listener Query Interval is the Maximum Response Delay inserted into
Multicast-Address-Specific Queries sent in response to Done messages, and is also the amount of
time between Multicast- Address-Specific Query messages. When the device receives an MLDv1
leave message or an MLDv2 state change report, it sends out a query and expects a response
within the time specified by this value. Using a lower value allows members to leave groups more
quickly. You can set the last listener query interval by entering a command such as the following.
BigIron RX(config)#ipv6 mld llqi 5
Syntax: ipv6 mld llqi <seconds>
Specify 1 – 10 for <seconds>.
