Setting the group membership time

You can set the group membership time for the default VRF or for a specified VRF. Group
membership time defines how long a group will remain active on an interface in the absence of a
group report. Possible values are from 5 through 26,000 seconds and the default value is 260
seconds.

To define an MLD group membership time of 2000 seconds, enter the following command.

Brocade(config)# ipv6 mld group-membership-time 2000

Syntax: [no] ipv6 mld group-membership-time 5-26000

To define an MLD group membership time of 2000 seconds for a specified VRF, enter the following
commands.

Brocade(config)# ipv6 router pim vrf blue

Brocade(config-ipv6-pim-router-vrf-blue)# ipv6 mld group-membership-time 2000

Syntax: [no] ipv6 router pim [vrf vrf-name]

The vrf parameter specifies the virtual routing instance (VRF) specified by the variable vrf-name.

Defining the maximum number of MLD group addresses

You can use the following run-time command to set the maximum number of MLD addresses for
the default VRF or for a specified VRF. To define this maximum for the default VRF, enter the
following command.

Brocade(config)# ipv6 mld max-group-address 1000

Syntax: [no] ipv6 mld max-group-address num

The num variable specifies the maximum number of MLD group addresses you want to make
available for the default VRF. If not defined by this command, the maximum value is determined by
available system resources.

To define this maximum 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-group-address 1000

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 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.
