Enabling the Flooding of Unregistered IPv6 Multicast Frames Globally

The following task enables the flooding of initial packets for unregistered IPv6 multicast groups until hardware entries are programmed. Once the hardware entries are programmed, packets are dropped for unregistered multicast groups.
  1. Note: If SDVoE is enabled for a VLAN, it must be disabled before attempting to enable the flooding of unregistered IPv6 Multicast frames.
    Enter global configuration mode.
    device# configure terminal
  2. Enable the flooding of unregistered IPv6 Frames.
    device(config)# ipv6 multicast flood-unregistered

The following example enables the flooding of unregistered IPv6 multicast frames globally.

device# configure terminal
device(config)# ipv6 multicast flood-unregistered

The following example disables the flooding of unregistered IPv6 multicast frames globally.

device# configure terminal
device(config)# no ipv6 multicast flood-unregistered
