Internet Group Management Protocol
Internet Group Management Protocol (IGMP) is a communications protocol that establishes multicast group memberships using IPv4
networks. OS10 supports IGMPv1, IGMPv2, and IGMPv3 to manage the multicast group memberships on IPv4 networks.
IGMP snooping
IGMP snooping uses the information in IGMP packets to 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 virtual local area
network (VLAN) interfaces.
Congure IGMP snooping
• Enable IGMP snooping globally using the ip igmp snooping enable command in CONFIGURATION mode. This command
enables IGMP snooping on all VLAN interfaces.
• (Optional) Disable IGMP snooping on specic VLAN interfaces using the no ip igmp snooping command in VLAN INTERFACE
mode.
• In a network, the snooping switch is connected to a multicast Router that sends IGMP queries. On a Layer 2 network that does not
have a multicast router, you can congure the snooping switch to act as querier. Use the ip igmp snooping querier command
in VLAN INTERFACE mode to send the queries.
• OS10 learns the multicast router interface dynamically based on the interface on which IGMP membership query is received. To assign a
multicast router interface statically, use the ip igmp snooping mrouter interface interface—type command in VLAN
INTERFACE mode.
• (Optional) Congure the IGMP version using the ip igmp version version-number command in VLAN INTERFACE mode.
