Configuring IP Multicast Routing
Configuring Optional Multicast Routing Features
DETAILED STEPS
To remove the switch as a member of the group, use the no ip igmp static-group group-address interface configuration
command.
EXAMPLE
The following example shows how to configure group address 239.100.100.101 on Ethernet interface 0:
interface ethernet 0
ip igmp static-group 239.100.100.101
Configuring Optional Multicast Routing Features

Configuring Session Directory Announcement Support
The MBONE (multicast backbone of the Internet) is the small subset of Internet routers and hosts that are interconnected
and capable of forwarding IP multicast traffic. Other multimedia content is often broadcast over the MBONE. Before you
can join a multimedia session, you need to know what multicast group address and port are being used for the session,
when the session is going to be active, and what sort of applications (audio, video, and so forth) are required on your
workstation. The MBONE Session Directory Version 2 (sdr) tool provides this information. This freeware application can
be downloaded from several sites on the World Wide Web, one of which is http://www.video.ja.net/mice/index.html.
SDR is a multicast application that listens to a well-known multicast group address and port for Session Announcement
Protocol (SAP) multicast packets from SAP clients, which announce their conference sessions. These SAP packets
contain a session description, the time the session is active, its IP multicast group addresses, media format, contact
person, and other information about the advertised multimedia session. The information in the SAP packet is displayed
in the SDR Session Announcement window.
Command Purpose
1. configure terminal Enter global configuration mode.
2. interface interface-id Specify the interface to be configured, and enter interface
configuration mode.
3. no shutdown Enable the port, if necessary. By default, UNIs and ENIs are
disabled, and NNIs are enabled.
4. ip igmp static-group group-address Configure the switch as a statically connected member of a
group.
By default, this feature is disabled.
5. end Return to privileged EXEC mode.
6. show ip igmp interface
[interface-id]
Verify your entries.
7. copy running-config startup-config (Optional) Save your entries in the configuration file.
