To define an MLD group membership time of 2000 seconds for a specified VRF, enter the following
commands.
device(config)# ipv6 router pim vrf blue
device(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.
device(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.
device(config)# ipv6 router pim vrf blue
device(config-vrf-blue)# address-family ipv6
device(config-vrf-blue-ipv6)# ipv6 mld max-group-address 1000
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.
device(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.
device(config)# ipv6 router pim vrf blue
device(config-ipv6-pim-router-vrf-blue)# ipv6 mld max-response-time 5
Syntax: [no] ipv6 router pim [ vrfvrf-name ]
The vrf parameter specifies the virtual routing instance (VRF) specified by the variable vrf-name .
