RE-S-1800X4-16G-S Use Case
Mission-Critical Data Center Spine Redundancy with RE-S-1800X4-16G-S
In a hyperscale data center running MX Series spine switches, IT architects install the RE-S-1800X4-16G-S as a hot-spare routing engine. Upon primary RE failure, automated switchover completes in under 50 ms, preserving uninterrupted BGP sessions for 200,000+ routes. Outcome: 40 % reduction in unplanned downtime, consistent 8 Tbps throughput, and seamless service continuity.
Enterprise Campus Core Routing Acceleration
A global enterprise deploys the RE-S-1800X4-16G-S in MX Series core routers to support 10,000+ remote VPNs, advanced policy-based routing, and IPv4/IPv6 dual-stack environments. Leveraging the quad-core 1.8 GHz CPU and 16 GB memory, route convergence time drops by 30 % and control-plane scalability doubles. Outcome: faster application roll-outs, improved SLAs, and streamlined campus-wide digital transformation.
5G Multi-Tenant Edge Aggregation for Service Providers
A Tier-1 service provider integrates RE-S-1800X4-16G-S modules into MX-Series edge routers to manage 5G backhaul and multi-tenant VRFs. The spare routing engine accelerates BGP/MPLS session recovery and firewall filter processing, handling over 200,000 routes with sub-5 ms latency. Outcome: guaranteed carrier-grade availability, simplified maintenance workflows, and scalable edge-to-core traffic handling.
