• Use the no version to remove any access list restriction.
• See ip igmp access-source-group.
Assigning a Multicast Group to an Interface
You can assign an interface to send and receive all traffic for a particular multicast group.
This feature enables you to control the IGMP traffic and to test the behavior of multicast
protocols in the network.
ip igmp static-group
• Use to send and receive all traffic for a multicast group from a specific interface.
• The interface sets no timers for this group.
• Example
host1:boston(config-if)#ip igmp static-group 225.1.2.3
• Use the no version to stop the interface from sending all traffic for the group.
• See ip igmp static-group.
Configuring Group Outgoing Interface Mapping
You can configure an IGMP interface to use a different outgoing interface (OIF) for
multicast-data-forwarding by applying an OIF map. When you configure an OIF map on
an IGMP interface, the map is applied to all IGMP membership requests that the interface
receives.
To configure OIF mapping on an interface:
1. Create an OIF map using the ip igmp oif-map command at the global level.
2. Apply the OIF map to an interface using the ip igmp apply-oif-map command.
To properly configure an interface used in the OIF map for multicast-data-forwarding
capability, you must configure the interface version as passive with the ip igmp version
command. You can either specify a passive interface as the OIF or specify the OIF as self
(to use the IGMP interface as the OIF) in the ip igmp oif-map command.
ip igmp apply-oif-map
• Use to apply the specified outgoing interface (OIF) map to the current interface.
• Example
host1(config-subif)#ip igmp apply-oif-map OIFMAP
• Use the no version to remove the outgoing interface map association from the interface.
• See ip igmp apply-oif-map.
