JRR200 Route Reflector

Architecture and Key Components

Junos Operating System

Junos OS is a reliable, high-performance, modular network

operating system that is supported across all of Juniper’s

physical and virtual routing, switching, and security platforms,

reducing the cost, complexity, and resources required to

implement and maintain a Juniper-based network. With

secure programming interfaces, the Juniper Extension Toolkit

(JET), versatile scripting support, and integration with popular

orchestration frameworks, Junos OS offers flexible options for

continuous delivery and DevOps-style management, helping

service providers unlock more value from the network.

Junos Routing Engine

By leveraging Junos OS, the JRR200 Appliance inherits all of

the native Junos OS features found across the Juniper routing,

switching, and security portfolio:

• BGP add-path enhancement provides a selective approach

to add-path for prefixes. Routing information base (RIB)

table sizes are reduced with policy-based selections

enabled for selected prefixes. Multiple paths to a

destination can be advertised, and communities allow add

paths tagged only for a specific community.

• Large BGP communities enable peering with new emerging

operators by supporting 4-byte AS numbers (RFC 6793).

Applying policies to large communities gives operators the

ability to effectively expand and govern their peering.

• Adaptive BGP update compression speeds BGP

convergence on large peer groups and multi-CP setups. By

adaptively sensing high CPU and I/O conditions, BGP data

volumes can be reduced by up to 80%.

• Optimal route reflection offers a way to advertise the

best path from a client view instead of the route reflector

perspective. Built on a client group implementation, it

offers effective scale without having to create more RIB

(also known as routing table) copies.

• Routing protocol process (rpd) provides the flexibility

required to write new protocols and integrate rpd with

SDN controllers. These networks support more options to

deploy services over large BGP-based networks, support

multivendor environments, and rapidly deploy customized

routing solutions.

Features and Benefits

The JRR200 brings simplicity, scalability, and reliability to the

management of demanding, high-growth BGP networks—all in a

compact form factor.

Operational Simplicity

By combining the leading software for VRR functionality on

a form factor optimized for space and power, the JRR200

eliminates the complexities of dealing with service hardware,

hypervisor software, and installation. All issues are handled

through a single source—the Juniper Networks Technical

Assistance Center (JTAC)—and the application comes pre-

installed to improve time to service delivery with ZTP.

Seamless Scalability

The JRR200 provides highly scalable environments with dense

8x10GbE port capacity and high throughput port connectivity.

Routing tables up to 50 million routing RIBs are also supported.

Ultimate Reliability

The JRR200 features dual redundant power supplies to ensure

reliability. The appliance also provides optimal power efficiency,

reducing power footprint with no sacrifice to scale or features.

Applications and Use Cases

The JRR200 offers tremendous flexibility, supporting multiple

use cases across network-based, cloud-based, and Clos fabric

designs.

Network-Based Route Reflector Design

JRR200 users can rapidly deploy a pre-integrated route

reflector that scales to meet the most demanding BGP network

requirements. Using advanced features, the best routes are

provided and services that run across the networks will ensure

the best possible customer experiences.
