Configuring IP Multicast Routing

Configuring Optional Multicast Routing Features

DETAILED STEPS
Command
1. configure terminal
2. interface interface-id
3. no shutdown
4. ip igmp static-group group-address
5. end
6. show ip igmp interface
[interface-id]
7. copy running-config startup-config
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 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.
Purpose
Enter global configuration mode.
Specify the interface to be configured, and enter interface
configuration mode.
Enable the port, if necessary. By default, UNIs and ENIs are
disabled, and NNIs are enabled.
Configure the switch as a statically connected member of a
group.
By default, this feature is disabled.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
(optional)—for MBONE multimedia conference
(optional)—to control bandwidth utilization.
