Route and protect WAN-connected enterprise sites with a Cisco Catalyst 8200 Series secure router built for the network edge. C8221-G2+ provides a routing platform for locations where branch, campus-edge, or distributed-site traffic transitions between local networks and upstream WAN services. Its stated role is secure routing rather than Ethernet switching or wireless access. Use this platform where routing policy and security controls need to be applied at the same edge location. It can serve as the routed boundary between a local LAN and WAN connectivity, helping network teams place traffic handling and security functions close to users, applications, and site resources. This role suits distributed environments that require consistent edge routing across multiple locations. The Catalyst 8200 Series designation places this router in Cisco's enterprise edge-routing family. Select the C8221-G2+ configuration when the deployment calls for a secure-router platform rather than a standalone switch, access point, or firewall-only appliance. Interface requirements, WAN handoff type, routing design, and required security services should be established as part of the site network design.
