JUNOS 10.4 Protected System Domain Configuration Guide
Objectives
Audience
xx
This guide is designed to provide an overview of the Juniper Networks JCS1200 Control
System and the concept of Protected System Domains (PSDs). The JCS1200 platform,
which contains up to 12 Routing Engines (or 6 redundant Routing Engine pairs) running
Junos OS, is connected to up to three T Series routers , including any combination of
T320 Core Routers, T640 Core Routers, and T1600 Core Routers.
The Junos OS running on a pair of redundant Routing Engines on a T Series router is
considered a Root System Domain (RSD). In the RSD configuration, you create a PSD
by assigning one or more Flexible PIC Concentrators (FPCs) on a T Series router to a
Routing Engine (or redundant Routing Engine pair) on the JCS1200 platform. Each PSD
has the same capabilities and functionality as a physical router, with its own control
plane, forwarding plane, and administration.
RSDs and PSDs can run different versions of Junos OS. Each RSD and PSD must be
running Junos OS Release 9.4 or later.
Different PSDs can share interfaces on a single Physical Interface Card (PIC) owned by
the RSD. The RSD and PSDs must be running Junos OS Release 9.3 or later.
NOTE: This guide documents Release 10.3 of the Junos OS. For additional
information about the Junos OS—either corrections to or information that
might have been omitted from this guide—see the software release notes at

This guide is designed for network administrators who are configuring and monitoring a
Juniper Networks T Series router and JCS1200 platform.
To use this guide, you need a broad understanding of networks in general, the Internet
in particular, networking principles, and network configuration. You must also be familiar
with one or more of the following Internet routing protocols:
Border Gateway Protocol (BGP)
Distance Vector Multicast Routing Protocol (DVMRP)
Intermediate System-to-Intermediate System (IS-IS)
Internet Control Message Protocol (ICMP) router discovery
Internet Group Management Protocol (IGMP)
Multiprotocol Label Switching (MPLS)
Open Shortest Path First (OSPF)
Protocol-Independent Multicast (PIM)
Resource Reservation Protocol (RSVP)
