Cisco ISR 4431 4GE 8 GB Flash 4 GB DRAM | Router, Enterprise — CON-L1NBD-C10016LG

Keep branch routing infrastructure covered when network continuity matters. This Cisco ISR 4431 support offering is aligned to a platform built with 4 Gigabit Ethernet interfaces, 3 NIM slots, 8 GB flash, and 4 GB DRAM, giving IT teams a service path for a router class designed to handle distributed enterprise traffic. For organizations running remote offices, retail sites, or regional hubs, ISR platforms sit at the center of WAN access, segmentation, and local resiliency. Support coverage helps reduce operational risk by keeping the router environment under a defined service umbrella, which is especially important when the device anchors voice, data, and application traffic for a site. The hardware profile suggests a branch-focused design with room for modular expansion through NIMs and enough memory and storage to support routing functions and configuration persistence. That makes this coverage relevant for teams that need predictable support terms around a critical edge router rather than a commodity replacement option. It is a practical choice when the cost of downtime exceeds the cost of maintaining a supported Cisco branch platform. Ideal For Supporting a branch router that connects remote offices to the WAN Covering a site gateway that carries voice, data, and application traffic Maintaining modular edge routing with NIM-based expansion Standardizing support for Cisco ISR deployments across distributed locations Why This Product 1 Supports a branch router rather than a basic access device 2 Covers a modular platform with 3 NIM slots 3 Aligns to a Cisco edge architecture built for WAN traffic 4 Provides support terms for a critical site gateway
