The Routing Engine is an Intel-based PC platform that runs Junos OS. Software processes
that run on the Routing Engine maintain the routing tables, manage the routing protocols
used on the device, control the device interfaces, control some chassis components, and
provide the interface for system management and user access to the device.
You must install at least one Routing Engine in the services gateway. You can install a
second Routing Engine if both Routing Engines are running Junos OS Release 10.0 or
later.
A second Routing Engine is required if you are using the dual chassis cluster control link
feature available in Junos OS Release 10.0 and later. The second Routing Engine does
not perform all the functions of a Routing Engine and does not improve resiliency or
redundancy. The second Routing Engine and the Switch Control Board (SCB) in which
it is installed do not constitute a Host Subsystem. The only function of the second routing
engine is to enable the hardware infrastructure that enables the Chassis Cluster Control
1 port on the services processing card (SPC) used for chassis cluster control links.
If you install only one Routing Engine in the services gateway, you must install it in the
slot in the front panel of SCB0. If you install a second routing engine to use the dual
chassis cluster control link feature, you install it in the slot in the front panel of SCB1.
