Setting the Maximum Number of MLD Group Addresses

You can change the maximum number of MLD group addresses for the default virtual routing and forwarding (VRF) instance or a specific VRF, globally or at the interface level.

Complete the following steps to set the maximum number of MLD addresses for a specific VRF.

  1. Enter global configuration mode. 
    device# configure terminal
  2. Specify the VRF. 
    device(config)# vrf vpn1
  3. Enter IPv6 address family mode. 
    device(config-vrf-vpn1)# address-family ipv6
  4. Set the maximum number of IGMP group addresses. 
    device(config-vrf-vpn1-ipv6)# ipv6 mld max-group-address 1000

The following example sets the maximum number of MLD group addresses for VRF VPN1 to 1000. 

device# configure terminal
device(config)# vrf vpn1
device(config-vrf-vpn1)# address-family ipv6
device(config-vrf-vpn1-ipv6)# ipv6 mld max-group-address 1000

The following example configures a maximum of 1000 MLD group addresses for a VE interface.

device# configure terminal
device(config)# interface ve 10
device(config-vif-10)# ipv6 mld max-group-address 1000
