ISR4461/K9 Overview
The Cisco ISR4461/K9 is Cisco’s highest-end branch office router, designed to deliver maximum performance, services integration, and investment protection for enterprises and service providers. With an aggregate throughput of up to 3Gbps, the ISR 4461 allows deployment of multiple concurrent services without performance degradation.
The Cisco ISR4461/K9 provides a flexible mix of fixed ports and modular slots for network interface modules (NIMs) and enhanced service modules, enabling concurrent services at gigabit speeds. It runs the Cisco IOS XE modular software, allowing on-demand activation of integrated services like application optimization, security, and voice/video.
With a performance-on-demand license, the router capacity can be doubled to 3Gbps aggregate forwarding without requiring new hardware. The Cisco ISR4461/K9 protects investments with an extensive array of WAN connectivity options, support for hardware stacking, and IPv6 readiness.
