For MLD snooping, solicited nodes have the IPv6 address form of FF02::1:Fxx:xxxx, where xx:xxxx consists of 24 bits of the host or VM MAC address. This allows 224 possible unique groups and if MLD snooping is enabled for IPv6 addresses, scaling the number of hosts and VMs on a network can deplete the number of multicast groups. Therefore, the ability to enable or disable MLD snooping for IPv6 addresses is necessary.
Note that a Neighbor Discovery Solicited Node is in the range of ff02::1:ff00:0/104 whereas a link-local address is in the range of ff02::/10. When link-local snooping is disabled, MLD snooping of ff02::1:ff00:0/104 is determined by the parameter no-snoop-nd|snoop-nd for the command mld-snooping-modify.
CLI (network-admin@Spine1)>mld-snooping-modify no-snoop-linklocal|snoop-linklocal no-snoop-nd|snoop-nd
By default, MLD snooping is disabled. If MLD snooping is enabled, snoop-linklocal and snoop-nd are enabled.
