Engine Board (CFEB-E) Description on page 10
The Routing Engine runs Junos OS. The software processes that run on the Routing Engine
maintain the routing tables, manage the routing protocols used on the router, control
the router's interfaces, control some chassis components, and provide the interface for
system management and user access to the router.
For a description of the Routing Engine's role in router architecture, see "M10i Routing
Engine Architecture Overview" on page 33.
NOTE: The M10i router supports the Routing Engine 400 and Routing Engine
850.
One or two Routing Engines can be installed into the midplane from the front of the
chassis, as shown in Figure 1 on page 6. If two Routing Engines are installed, the
High-Availability Chassis Manager (HCM) determines which is the master and which is
backup (in standby mode and so performs no functions). By default, the Routing Engine
in the slot labeled is the master. To change the default master Routing Engine,
RE0
include the appropriate
[edit chassis redundancy routing-engine]
configuration, as described in the section about Routing Engine redundancy in the Junos
OS System Basics Configuration Guide.
NOTE: If two Routing Engines are installed, they must both be the same
hardware model.
The Routing Engine is hot-pluggable, as described in "M10i Field-Replaceable Units
(FRUs)" on page 99. If two Routing Engines are installed, removal or failure of the backup
Routing Engine does not affect router function. Removal or failure of the master Routing
Engine affects forwarding and routing based on the high availability configuration:
