XRE200 EXTERNAL
ROUTING ENGINE
DATASHEET
Product Overview
The XRE200 External Routing Engine
delivers the additional processing
power required to build Virtual Chassis
configurations based on the EX8200
line of Ethernet switches to support
more than 1400 GbE or more than 1200
10GbE connections.
Product Introduction
The Juniper Networks® XRE200 External Routing Engine is a purpose-built, server-class
appliance that works with internal Routing Engines (REs) on the Juniper Networks
EX8200 line of Ethernet switches to create a highly resilient architecture for supporting
Virtual Chassis configurations based on the EX8200 line of modular switches.
By externalizing control plane functionality and separating it from the data plane running
on the actual switch fabric, the XRE200 implements a highly reliable design that includes
no single point of failure. The result is a scalable solution that provides the additional
processing power required to manage an EX8200-based Virtual Chassis configuration1.
Juniper ’s Virtual Chassis technology enables multiple interconnected switches to operate
as a single, logical device. In the EX8200 line of Ethernet switches, Virtual Chassis
technology greatly simplifies data center and campus core network configurations,
management, and troubleshooting. Virtual Chassis technology in the EX8200 switches
also minimizes or eliminates the need for Spanning Tree Protocol (STP) while increasing
network performance by enabling full utilization of all network uplinks.
Product Description
The XRE200 is a 2RU device that includes two slots for supporting 1GbE Virtual Chassis
Control Interface (VCCI) modules. Two VCCI module options are available:
• 4-port 10/ 100/100BASE-T RJ-45 module (included with the base XRE200 system)
• 4-port 1000BASE-X GbE SFP module (optional for extending the Virtual Chassis
configuration up to 40 km)
On the front panel, the XRE200 includes an LCD screen2 for reporting device status at a
glance or performing device configuration via a menu-driven screen; a 10/100/ 100BASE-T
RJ-45 port for XRE-to-XRE or XRE-to-Virtual Chassis connections; a console port for out-
of-band management; and a USB drive for file storage.
Additional front panel slots are also available for supporting redundant 160 GB hard drives
for providing extra processing power. On the back panel, the XRE200 includes redundant,
hot-swappable 250 W AC power supplies and redundant, hot-swappable fans.
Internally, the XRE200 includes a 2.1 GHz Intel Core 2 Duo processor with 2 MB L2 cache,
4 GB DRAM, and 4 GB of flash memory.

Architecture and Key Components
Building an EX8200-based Virtual Chassis configuration requires
two 8-slot Juniper Networks EX8208 Ethernet Switches, two 16-
slot EX8216 Ethernet Switches, or a combination of both, and
two XRE200 devices to provide an active/standby pair for control
plane and management plane redundancy.
Ports on the VCCI modules connect to the EX8200 internal REs,
either the EX8208-SRE320 or EX8216-RE320. One internal RE
from each EX8200 chassis is connected to the active XRE200,
while the second internal RE is connected to the standby XRE200.
The two XRE200 devices can also be connected to each other
directly via GbE interfaces.
An optional 1000BASE-X fiber VCCI module can be used to
connect the active and standby XRE200 devices in environments
where the distance between them exceeds the maximum span
of unshielded twisted pair cable—for example, when the EX8200
Virtual Chassis configuration is spread across two buildings.
Juniper Networks Junos® operating system high availability (HA)2
features such as GRES, NSR, and nonstop bridging (NSB) are
enabled on the XRE200 devices in a Virtual Chassis configuration.
In the event of an active XRE200 failure, the standby XRE200
assumes the active role without impacting network state or
forwarding behavior. Junos OS HA features ensure that the state of
the Virtual Chassis, L2/L3 protocols, and forwarding information
are not lost.
In addition, all Junos OS control plane protocols running on an
EX8200 Virtual Chassis configuration—including 802.3ad, OSPF,
Internet Group Management Protocol (IGMP), Physical Interface
Module (PIM), and BGP—also run on the XRE200, providing
control plane scalability for large core deployments. The EX8200
and XRE200 use the Virtual Chassis Control Protocol to exchange
Virtual Chassis state information.
XRE200 Features and Benefits
In addition to control plane scalability, the XRE200 ensures that if one
or more switches in the Virtual Chassis configuration lose connectivity
to the adjacent chassis, access switches connected to the EX8200
Virtual Chassis do not lose connectivity with the network.
The XRE200 also ensures that traffic flowing from one access
switch to any other access switch or to any core/WAN router
connected to the same EX8200 Virtual Chassis configuration are
not affected if the intra-Virtual Chassis connection fails.
Junos Operating System
The XRE200 runs the same Junos OS used by the Juniper Networks
EX Series Ethernet Switches, as well as all Juniper Networks routers
and Juniper Networks SRX Series Services Gateways. By utilizing a
common operating system, Juniper Networks delivers a consistent
implementation and operation of control plane features across
all products. To maintain that consistency, Junos OS adheres to a
highly disciplined development process that uses a single source
code, follows a single quarterly release train, and employs a highly
available modular architecture that prevents isolated failures from
bringing down an entire system.
These attributes are fundamental to the core value of the
software, enabling all Junos OS-powered products to be updated
simultaneously with the same software release. All features are
fully regression tested, making each new release a true superset
of the previous version. Customers can deploy the software with
complete confidence that all existing capabilities are maintained
and operate in the same way.
