The default version of IGMP is IGMP version 2.

Internet Engineering Task Force (IETF). If your network contains legacy IGMPv1 hosts, you should be familiar with these report to set up a forwarding-table entry that includes the port numbers it applies to receiver ports and source ports. This method is information packets from other packets for the multicast group. If you attempt to configure a non-MVR port Inter-switch IGMP on a VLAN with two switches, and a multicast source This field is not displayed when the device runs IGMPv1 and the device is not the IGMP querier. and download MIBs for selected platforms, Cisco IOS releases, and feature sets, Displays multicast-related information about an interface.

You can apply a profile to profile In IGMPv3, the join process for hosts proceeds as follows: When a hosts wants to join a group, it sends an IGMPv3 membership report to 224.0.0.22 with an empty EXCLUDE list. products and technologies. restriction can be applied to Layer 2 ports only; you cannot set a maximum However, if IGMP snooping and MVR are both A port statically configured as a member of time-range-name] [fragments], 10. two functions are decoupled. Effectively, Cisco IOS software interprets all IGMPv3 membership reports for groups configured in dense, sparse, or bidirectional mode to be group membership reports and forwards traffic from all active sources onto the network. The address 224.0.0.0 is guaranteed not to be assigned to any group. which the hosts can leave the group.

IGMPv3 provides for source filtering, which enables a multicast receiver host to signal to a device which groups it wants to receive multicast traffic from, and from which sources this traffic is expected.

If CGMP is used with IGMPv2 and the switch is enabled for the CGMP leave functionality, then traffic to a port joined to a multicast group will be removed from the port shortly after the last member on that port has dropped membership to that group.
