IPv6 MLD Commands
IGMP/MLD Snooping is Layer 2 functionality but IGMP/MLD are Layer 3 multicast protocols.
It requires that in a network setup there should be a multicast router (which can act as a
querier) to be present to solicit the multicast group registrations. However some network
setup does not need a multicast router as multicast traffic is destined to hosts within the same
network. In this situation, the 7000 series has an IGMP/MLD Snooping Querier running on
one of the switches and Snooping enabled on all the switches. For more information, see
IGMP Snooping Configuration Commands
on page
146 and
MLD Snooping Commands
on
page
158.
