expanded control plane capacity without sacrificing any forwarding slots in the T Series
router. All memory-intensive processing occurs on the Routing Engines on the JCS chassis,
whereas the FPCs on the T Series router are dedicated to efficient high-speed forwarding.

Root System Domains
The Root System Domain (RSD) is the Junos OS running on a pair of redundant Routing
Engines on a T Series router connected to the switch fabric on the JCS1200 platform.
The configuration on these Routing Engines provides:
•
The RSD identifier
•
The parameters used to create Protected System Domains (PSDs) under the RSD,
namely:
•
Which Routing Engine or redundant Routing Engine pair on the JCS1200 platform is
assigned to the PSD.
•
Which Flexible PIC Concentrator (FPC) or FPCs on the T Series router are assigned
to the PSD.
Because you can connect up to three T Series routers to the JCS1200 chassis, you can
configure up to three RSDs. The PSD identifiers must be unique for each RSD. That is,
PSD1 can only belong to RSD1, and not to RSD2 or RSD3.

Protected System Domains
A Protected System Domain (PSD) is a redundant Routing Engine pair (or single Routing
Engine) on the JCS1200 platform matched with one or more Flexible PIC Concentrators
(FPCs) on a T Series router. In Figure 1 on page 5, FPC1 and FPC2 and the Routing Engines
in slots 1 and 2 belong to PSD1. In contrast, PSD2 is made up of the FPCs in slots 3 and 4
on the T Series router and the Routing Engines in slots 3 and 4 on the JCS1200 chassis.
