mld-router-show
Multicast Listener Discovery (MLD) is a Layer 3 multicast protocol used between IPv6 hosts and routers similar to how IGMP is used for IPv4. MLD snooping allows a switch to examine MLD packets and make forwarding decisions based on their content.
MLD snooping constrains IPv6 multicast traffic at Layer 2 by configuring Layer 2 LAN ports dynamically to forward IPv6 multicast traffic only to those ports that want to receive it.
The default behavior, when MLD Snooping is not configured, multicast traffic is forwarded to all the switch ports, impacting switch performance.
