Internet group management protocol
Internet group management protocol (IGMP) is a communications protocol that hosts use on IPv4 networks to establish multicast group
memberships.
IPv6 networks use Multicast listener discovery (MLD) to manage multicast groups.
OS10 supports IGMPv2 and MLDv1 to manage the multicast group memberships on IPv4 and IPv6 networks.
IGMP snooping
IGMP snooping enables switches to use the information in IGMP packets and generate a forwarding table that associates ports with
multicast groups. When switches receive multicast frames, they forward them to their intended receivers.
OS10 supports IGMP snooping on VLAN interfaces and sends out query packets to VLAN member ports.
Congure IGMP snooping
• Enable IGMP snooping globally with the ip igmp snooping enable command in the CONFIGURATION mode. This command
enables both IGMPv2 and MLDv1 snooping on all VLAN interfaces.
