Before You Begin; Configuring A Multicast Network With A Configuration Editor; Configuring Sap And Sdp - Juniper J2300 User Manual

J-series™ Services Router User Guide

Before You Begin

Before you begin configuring a multicast network, complete the following tasks:

Configuring a Multicast Network with a Configuration Editor

To configure the Services Router as a node in a multicast network, you
must perform the following tasks marked (Required) .
For information about using the J-Web and CLI configuration editors, see
"Using J-series Configuration Tools" on page 127.

Configuring SAP and SDP

Multicast session announcements are handled by two protocols, the Session
Announcement Protocol (SAP) and Session Description Protocol (SDP).
These two protocols display multicast session names and correlate the
names with multicast traffic. Enabling SDP and SAP allows the router to
receive announcements about multimedia and other multicast sessions from
sources. Enabling SAP automatically enables SDP.

Configuring a Multicast Network with a Configuration Editor
If you do not already have a basic understanding of multicast, read "Multicast
Overview" on page 461.
Determine whether the Services Router is directly attached to any multicast
sources. Receivers must be able to locate these sources.
Determine whether the Services Router is directly attached to any multicast
group receivers. If receivers are present, IGMP is needed.
Determine whether to use the sparse, dense, or sparse-dense mode of
multicast operation. Each mode has different configuration considerations.
Determine the address of the rendezvous point (RP) if sparse or sparse-dense
mode is used.
Determine whether to locate the RP with the static configuration, bootstrap
router (BSR), or Auto-RP method.
Determine whether to configure multicast to use its own reverse-path
forwarding (RPF) routing table when configuring PIM in sparse, dense, or
sparse-dense modes.
