Multicast Listener Discovery and source-specific multicast protocols 4
Syntax: [no] vrf vrf-name
Syntax: [no] address-family ipv6
Syntax: [no] ipv6 mld max-group-address num
The vrf parameter specifies the virtual routing instance (VRF) specified by the variable vrf-name.
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.
Brocade(config)# ipv6 mld max-response-time 5
Syntax: [no] ipv6 mld max-response-time seconds
The seconds variable specifies the MLD maximum response time in seconds. You can specify from
1 through 25 seconds. The default is 10 seconds.
To define the maximum amount of time a multicast listener has to respond to queries for a
specified VRF, enter the following commands.
Brocade(config)# ipv6 router pim vrf blue
Brocade(config-ipv6-pim-router-vrf-blue)# ipv6 mld max-response-time 5
Syntax: [no] ipv6 router pim vrf [vrf-name]
The vrf parameter specifies the virtual routing instance (VRF) specified by the variable vrf-name.
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.
Brocade(config)# ipv6 mld query-interval 50
Syntax: [no] ipv6 mld query-interval seconds
The seconds variable specifies the MLD query interval in seconds. You can specify from 2 through
3600 seconds. The default value is 125 seconds.
To define the frequency at which MLD query messages are sent for a specified VRF, enter the
following commands.
Brocade(config)# ipv6 router pim vrf blue
Brocade(config-ipv6-pim-router-vrf-blue)# ipv6 mld query-interval 50
Syntax: [no] ipv6 router pim [vrf vrf-name]
The vrf parameter specifies the virtual routing instance (VRF) specified by the variable vrf-name.
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.
