The ISR 4321 platform routes traffic between your network and the rest of the world branch offices, WAN aggregation, inter-VLAN gateways and service edges. Professionally decommissioned, tested and factory-reset.

Series Positioning

ISR 4321 sits in Cisco’s routing lineup for organizations that need WAN connectivity with routing, QoS and security features in one chassis the kind of gear that runs quietly for a decade.

Why Not Consumer Gear

Enterprise routers handle concurrent sessions, route tables and uptime expectations that consumer boxes were never designed for. When the office depends on the link, this is the class of hardware you want on it.
