4.9.2 MLD Snooping Configuration
This section provides MLD Snooping-related configuration. The MLD is for IPv6 Multicast Snooping. The
difference between the 2 IGMP and MLD is that the IGMP is applied to IPv4 Multicast stream while the
MLD is applied to IPv6 Multicast stream. While configuring the MLD Snooping configuration, the only thing
you need to understand is the IPv6 packet format.

Router Port
Specify which ports act as router ports. A router port is a port on the Ethernet switch that leads toward the
Layer 3 multicast device or MLD querier. Normally, the router port is the uplink port to the upper L3 Router
or IGMP Querier. For example, in below figure, the green ports of the 2 switches are Router ports.
