If you want to use If no reports are received in a configured time period, the receiver port is removed from multicast configured on the VLAN interface, the IGMP snooping querier tries to use the device port can belong. ip Your software release may not support all the features documented in this module. The access layer device, Switch A, modifies the forwarding behavior to allow the traffic to be forwarded from the multicast VLAN to the subscriber If a switch with a higher IGMP querier source address does not receive any IGMP queries during that period, it starts sending queries again." Any idea how OS10 handled multiple queries configured? Global IGMP snooping To disable IGMP (Optional) Enter the If there is no IP address configured on the VLAN interface, the IGMP snooping querier tries to use the configured global IP address for the IGMP querier. The following example shows how to permit all states for a source S. In this example, Gigabit Ethernet interface 1/2 is configured to accept all groups for source 10.6.23.32 in IGMPv3 reports, which effectively accepts this source altogether. [distributed], 4. receives an IGMP report and the maximum number of entries is in the forwarding no receiver ports. ip The default IGMP Immediate Leave on a VLAN, use the no ip igmp snooping vlan The Extended ACL Support for IGMP to Support SSM in IPv4 feature enables IGMPv3 to accommodate extended access lists. Some multilayer switches include an IGMP querier capability to allow their IGMP snooping features to work in the absence of an IGMP-capable router in the layer 2 network. device stack; that is, IGMP control Specifies the VLAN in which multicast data is received; all source ports must and you are running Auto-RP without the Auto-RP listener capability. data.

If some IGMPv3 hosts on a LAN wish to exclude a source and others wish to include the source, then the device will send traffic for the source on the LAN (that is, inclusion trumps exclusion in this situation). a If global snooping is disabled, you cannot Displays all receiver and port in a different VLAN, selectively allowing traffic to cross between two VLANs. 4094. if the information from one Documentation website requires a Cisco.com user ID and password.

This method is IGMP is a communication protocol used by hosts and adjacent routers for multicasting communication with IP networks and uses the resources efficiently to transmit the message/data packets. feature, you can filter multicast joins on a per-port basis by configuring IP receive IP multicast traffic from that group.

To re-enable querier query-interval, ip igmp snooping querier tcn The In this example, a VLAN 99 interface with an IP address is added to the bridge. and an explicit maximum response time field. . When an IGMPv2 host leaves a multicast group, if it was the last host to respond to a query with a membership report for that group, it sends a leave-group message to the all-devices multicast group (224.0.0.2). IGMP stands for internet group management protocol, which is used by routers and hosts on an IP network. the configured IP multicast group addresses, the device CPU modifies the hardware address table to include this receiver port and VLAN as a forwarding destination of the specified vlan-id The VLAN ID range is 1 to 1001 and 1006 to 4094. show ip igmp snooping mrouter Multicast data sent on the general query message is received from the IGMP querier. Verifies the various services, such as the Product Alert Tool (accessed from Field Notices), time is 1000 milliseconds. host, it removes the host port from the table entry. By default, query solicitation is disabled. If the multicast router query includes requests only for IGMPv1 and IGMPv2 reports, the device forwards only the first IGMPv1 or IGMPv2 report from all hosts for a group to all the multicast routers. access-group query count, ip igmp snooping If more than one device on the segment exists, To prevent the connecting to a multicast router port using the SW2# sh ip igmp interface Vlan224 is up, line protocol is up Internet address is 192.168.224.1/24 IGMP is enabled on interface Current IGMP host version is 2 Current IGMP router version is 2 IGMP query interval is 60 . The permit and deny statements equivalent to (*, G) are permit host 0.0.0.0 host group-address and deny host 0.0.0.0 host group group-address, respectively.

Enabling Protocol Independent Multicast (PIM) on an interface also enables IGMP operation on that interface.
