4-rack-unit modular router platform supporting up to eight shared port adapters and one route processor plus an embedded services processor slot. Modular architecture separates control and data planes to enable capacity upgrades and service insertion without full chassis replacement. Delivers up to 40 Gbps aggregate forwarding capacity and supports IOS XE software with software-based redundancy and high-availability deployment patterns. Typical roles include WAN edge aggregation, internet gateway, L2TP access concentrator (LAC/LNS), L3VPN provider edge, or route-reflector deployments.
