Cisco ISR 4321 2GE 4 GB DRAM Router

Keep critical branch traffic on line with the Cisco ISR 4321, a compact integrated services router designed for secure WAN edge deployments. Dual Gigabit Ethernet ports provide straightforward uplink and LAN connectivity, while two NIM slots give you room to adapt the platform to changing site requirements. With 4 GB DRAM and 4 GB flash, the router has the memory and storage headroom needed for routing services, configuration retention, and operational stability. This model fits organizations that need more than basic connectivity. It is built for branch environments where network control, segmentation, and predictable performance matter more than low-cost consumer hardware. The ISR 4321 platform is a strong fit for teams standardizing on Cisco infrastructure and looking for a router that can anchor a remote office, retail site, or small facility without overbuilding the edge. The value is in the balance: a compact footprint, expansion flexibility, and Cisco’s enterprise routing architecture in a form factor suited to distributed deployment. For infrastructure teams, that means fewer compromises when the branch needs to stay connected through changing traffic demands and operational constraints.
