Configuring sdr Listener Support
The MBONE 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.
Enabling sdr Listener Support (CLI)
By default, the device does not listen to session directory advertisements.
This procedure is optional.
