CISCO1921/K9 Use Case
Secure Multi-Site Branch Connectivity with VPN and MPLS
Scenario: A retail chain needs to interconnect 25 branch locations to its data center over a mixed MPLS and Internet backbone. The Cisco ISR 1921/K9, with its 2 GE ports, 2 EHWIC slots and IP Base feature set, terminates site-to-site IPsec VPN tunnels and integrates seamlessly with existing MPLS circuits. Outcome: End-to-end encryption and dynamic routing reduce WAN complexity by 40 %, deliver sub-5 ms failover for mission-critical POS and inventory traffic, and consolidate security policies centrally for PCI-DSS compliance.
Enterprise-Grade IoT Edge Gateway for Real-Time Data Aggregation
Scenario: A manufacturing plant deploys hundreds of sensors and PLCs on the shop floor. By equipping each cell with a Cisco 1921/K9 router, leveraging its 2 EHWIC slots for dedicated serial and IO modules and 2 GE uplinks, the operations team creates a secure, high-throughput edge network. Outcome: Local data preprocessing and encrypted backhaul to the SCADA system cut cloud ingestion latency by 60 %, simplify device onboarding, and enable predictive maintenance analytics with five-nines availability.
Cloud-Ready SD-WAN Branch Router for Optimized Application Performance
Scenario: A professional services firm requires dynamic path selection for SaaS and IaaS applications across multiple Internet links. Deploying the Cisco 1921/K9 with the IP Base license enables zero-touch provisioning for Cisco SD-WAN, leverages dual GE interfaces for active/backup Internet circuits, and uses 512 MB DRAM for control-plane resiliency. Outcome: Automatic traffic steering improves application SLAs by 30 %, lowers bandwidth costs by 25 %, and accelerates cloud onboarding with centralized orchestration through Cisco vManage.
