Multicast Listener Discovery and source-specific multicast protocols 4<br />
Syntax: [no] vrf vrf-name<br />
Syntax: [no] address-family ipv6<br />
Syntax: [no] ipv6 mld max-group-address num<br />
The vrf parameter specifies the virtual routing instance (VRF) specified by the variable vrf-name.<br />
Setting the maximum response time<br />
You can define the maximum amount of time a multicast listener has to respond to queries by<br />
entering a command such as the following.<br />
<strong>Brocade</strong>(config)# ipv6 mld max-response-time 5<br />
Syntax: [no] ipv6 mld max-response-time seconds<br />
The seconds variable specifies the MLD maximum response time in seconds. You can specify from<br />
1 through 25 seconds. The default is 10 seconds.<br />
To define the maximum amount of time a multicast listener has to respond to queries for a<br />
specified VRF, enter the following commands.<br />
<strong>Brocade</strong>(config)# ipv6 router pim vrf blue<br />
<strong>Brocade</strong>(config-ipv6-pim-router-vrf-blue)# ipv6 mld max-response-time 5<br />
Syntax: [no] ipv6 router pim vrf [vrf-name]<br />
The vrf parameter specifies the virtual routing instance (VRF) specified by the variable vrf-name.<br />
Setting the query interval<br />
You can define the frequency at which MLD query messages are sent. For example, if you want<br />
queries to be sent every 50 seconds, enter a command such as the following.<br />
<strong>Brocade</strong>(config)# ipv6 mld query-interval 50<br />
Syntax: [no] ipv6 mld query-interval seconds<br />
The seconds variable specifies the MLD query interval in seconds. You can specify from 2 through<br />
3600 seconds. The default value is 125 seconds.<br />
To define the frequency at which MLD query messages are sent for a specified VRF, enter the<br />
following commands.<br />
<strong>Brocade</strong>(config)# ipv6 router pim vrf blue<br />
<strong>Brocade</strong>(config-ipv6-pim-router-vrf-blue)# ipv6 mld query-interval 50<br />
Syntax: [no] ipv6 router pim [vrf vrf-name]<br />
The vrf parameter specifies the virtual routing instance (VRF) specified by the variable vrf-name.<br />
Setting the last listener query interval<br />
The Last Listener Query Interval is the Maximum Response Delay inserted into<br />
Multicast-Address-Specific Queries sent in response to Done messages, and is also the amount of<br />
time between Multicast- Address-Specific Query messages. When the device receives an MLDv1<br />
leave message or an MLDv2 state change report, it sends out a query and expects a response<br />
within the time specified by this value. Using a lower value allows members to leave groups more<br />
quickly. You can set the last listener query interval by entering a command such as the following.<br />
