Redundant limited version performed well during failover testing. No traffic disruption.
High availability worked as expected. Stable control plane throughout.
Reliable redundant routing engine for compliance constrained networks.
Failover was smooth and predictable. Good redundancy option.
Provides added resilience without complexity. Satisfied with performance.
The REMX2K-X8-64G-LT-R is a redundant routing engine and control board for Juniper MX2010 and MX2020 routers, featuring an 8-core 2.3 GHz CPU and 64 GB of DRAM with limited encryption support.
This routing engine is fully compatible with Juniper MX2010 and MX2020 chassis, supporting both single- and dual-engine redundant configurations.
It includes an 8-core 2.3 GHz processor, 64 GB memory, dual management ports, redundant power paths, and limited encryption capability for regulated environments.
Limited encryption offers restricted cryptographic functions compliant with export regulations, enabling basic IPsec and MACsec features without full commercial encryption.
By deploying two identical routing engines in active/passive mode, failover occurs automatically on hardware or software faults, ensuring continuous network operation.
Yes. With the proper license and Juniper approved procedures, you can replace your existing engine with the REMX2K-X8-64G-LT-R for improved performance and redundancy.
You gain up to 2.3 GHz processing per core and 64 GB of DRAM, boosting routing table scale, control-plane throughput, and overall packet-forwarding performance.
The control board is equipped with 64 GB of DDR4 DRAM to handle large BGP tables, MPLS labels, and high-performance packet processing.
Yes. The limited encryption version complies with EAR (Export Administration Regulations) and other regional export controls while supporting essential secure tunneling.
It requires Junos OS Release 18.2R1 or later to ensure full feature compatibility, performance optimization, and security fixes.
Power down the MX chassis, slide the engine into the designated FEM slot, secure the retention screws, then power on and validate status via CLI or J-Web.
Juniper offers a standard one-year hardware warranty with 24×7 J-Care support options, including next-business-day sparing and software updates.
Lead times vary by region, but standard orders ship within 2–5 business days; expedited shipping options are available for critical deployments.
Yes. Returns are accepted within 30 days of delivery under Juniper’s standard RMA policy, provided the unit is in original condition.
Its redundant architecture, advanced CPU cores, and ample memory reduce control-plane bottlenecks and ensure seamless failover during maintenance or faults.
Use Junos CLI commands such as “show chassis routing-engine” or check the J-Web dashboard for real-time CPU, memory, and redundancy status.
