RE-S-1800X4-16G Juniper Routing Engine - Quad Core 1.8GHz/16G Memory
Juniper RE-S-1800X4-16G Routing Engine
High-Performance Control Plane Module for MX-Series 3D Universal Edge Routers
The Juniper Networks RE-S-1800X4-16G Routing Engine is a high-performance control plane module engineered for Juniper MX240, MX480, and MX960 routers, delivering the processing power and scalability required for modern service provider and enterprise networks. Designed to run Junos OS (64-bit), this routing engine ensures efficient handling of complex routing protocols, large-scale subscriber management, and high-capacity network operations.
Powered by a 1.8 GHz Intel quad-core processor, the RE-S-1800X4-16G distributes control plane tasks across multiple cores, significantly improving routing protocol convergence times and overall system responsiveness. With 16 GB of DDR3 memory, it supports multiple full Internet routing tables, large configuration databases, and high-density BGP peering environments without performance degradation.
The module includes dual 8 GB internal NAND flash storage, providing redundant boot capability to ensure system reliability and continuous operation. It is fully compatible with SCB, SCBE, and SCBE2 switch control boards, allowing seamless integration into existing MX Series deployments while supporting future scalability.
Built for high availability, the RE-S-1800X4-16G supports advanced Junos features such as Graceful Routing Engine Switchover (GRES), Nonstop Active Routing (NSR), and Unified In-Service Software Upgrade (ISSU). When deployed in a dual Routing Engine configuration, it enables stateful failover and uninterrupted network operations, making it ideal for mission-critical environments.
With robust support for BGP, OSPF, IS-IS, MPLS, L2VPN, and L3VPN, along with high-scale Broadband Network Gateway (BNG) capabilities, the Juniper RE-S-1800X4-16G is optimized for service provider edge networks, ISP backbones, and large enterprise infrastructures that demand reliability, scalability, and high-performance routing.

FAQs:
Q1. Does this Routing Engine work in the MX80 or MX104?
No. The RE-S-1800X4-16G is a slot-based module designed for the larger modular MX240, MX480, and MX960 chassis. The MX80 and MX104 have their own specialized internal or fixed routing engines.
Q2. What is the difference between the 8G and 16G versions?
The hardware is identical except for the amount of installed RAM. The 16G version is highly recommended for routers acting as BGP Route Reflectors or those carrying multiple full Internet tables.
Q3. Do I need a specific Switch Control Board (SCB) for this RE?
This RE is versatile and compatible with the standard SCB, SCBE, and SCBE2. However, it must be physically seated into the SCB module before being inserted into the chassis.
Q4. Does this support 64-bit Junos?
Yes. The quad-core architecture and 16GB of memory are optimized to run the 64-bit version of Junos OS, which allows the system to utilize all available RAM effectively.
Q5. Can I mix this RE with an older RE-S-1300 or RE-S-2000 in a redundant setup?
No. For GRES and NSR to function correctly, both Routing Engines in a chassis must be of the same model and have the same amount of memory.
