Cisco ESR6300 Embedded Series Router

An embedded router that's ready for action

The Cisco ESR6300 Embedded Series Router enables third-party systems integrators to build custom Gigabit Ethernet routing solutions. It is optimized for size, weight, and power to operate fully in extreme, harsh environments. With Cisco IOS XE, it provides highly secure data, voice, and video communications to stationary and mobile network nodes. The ESR-6300 also offers Cisco Radio Aware Routing (RAR) to improve network reliability.

Features and benefits

Radio Aware Routing

RAR addresses several challenges involved in merging IP routing and radio communications in mobile networks. This technology has applications in the defense industry and in state and local government for search and rescue, law enforcement, and disaster assessment.

Cisco Trustworthy Systems

The onboard Cisco Trust Anchor module plus image signing, secure boot, and run-time defenses help to ensure that the code running on the Cisco ESR6300 is authentic, unmodified, and operating as intended.

Simplified integration

At 3 inches by 3.75 inches, the ESR6300 is smaller than its predecessors, making it easier to integrate in compact solutions. It is hardened for extreme temperatures, shock, and vibration to achieve a high standard of reliability.

Flexible options

The ESR6300 provides 2 WAN ports of Gigabit Ethernet that give you a choice of media type and 4 LAN ports of Gigabit Ethernet with PoE/PoE+-ready options.

Streamlined management with IOS-XE

Cisco IOS XE is highly programmable, with open and standards-based APIs and next-generation, multilayer security built in. This unified software stack is ideal for process and workflow automation, so you can qualify and deploy new services faster.

A boost for network management

Use Cisco Catalyst Center or Cisco Catalyst SD-WAN Manager to enjoy scale, simplicity, and unified management for extending the enterprise network to a distributed IoT deployment.

How you can use it

Defense and aerospace

Deploy ESR6300s to build advanced tactical networks that provide highly secure and reliable high-speed connectivity. Deliver highly secure broadband for voice, video, and data communication. Integrators can use ESR6300s in the communication systems of military hardware in vehicles, aircraft, helicopters, drones, and ships.

Oil and gas

Oil and gas companies need to monitor and analyze data from some of the remotest, harshest environments in the world. Use the ESR6300 to build reliable networks that can monitor high-value assets and collect data for real-time data analysis. Drive efficiencies and increase safety while operating in remote and hazardous locations.


Install the ESR6300 where your applications require high-quality voice, video, and data connectivity: in trains, commercial airplanes, and self-driving vehicles. Integrators can build routers with custom interfaces and suitable levels of mechanical ruggedization—ingress protection, temperature, shock vibration—based on application needs.
