MikroTik CCR2116-12G-4S+ — Cloud Core Router 12x Gigabit Ethernet, 4x10G SFP+ | The 16-Core Routing Powerhouse That Redefines High-Throughput Network Performance

The Router That Thinks at 16-Core Speed — So Your Network Never Has to Wait

There is a fundamental difference between a router that handles your network’s demands and a router that obliterates them. Between infrastructure that keeps pace with traffic and infrastructure that runs so far ahead of it that throughput, latency, and packet loss become irrelevant concerns rather than daily firefighting exercises. Between a device that manages your routing table and one that processes it at speeds that make every connected user, every latency-sensitive application, and every high-bandwidth workload perform at its absolute theoretical maximum.

The MikroTik CCR2116-12G-4S+ is that second router — in every dimension that matters.

Built around the formidable Annapurna Labs Alpine v3 AL73400 16-core processor, equipped with a generous 16GB of DDR4 RAM, delivering routing throughput that competes directly with enterprise-grade equipment costing multiples of its price, and running MikroTik RouterOS v7 — the most feature-complete, endlessly configurable network operating system available to network professionals worldwide — the CCR2116-12G-4S+ is the routing platform that ISPs, data centres, managed service providers, enterprise network architects, and technically sophisticated organisations have been waiting for from MikroTik’s Cloud Core Router series.

Twelve Gigabit Ethernet ports for flexible WAN and LAN connectivity. Four dedicated 10-Gigabit SFP+ ports for high-speed uplinks, peering connections, and backbone integration. Hardware-accelerated encryption for IPsec VPN performance that software routing solutions cannot approach. And the complete MikroTik RouterOS feature ecosystem — BGP, OSPF, MPLS, VXLAN, CAPsMAN, traffic shaping, firewall, and hundreds of additional capabilities — running on a platform with the raw processing muscle to execute every feature simultaneously without compromise.

This is the router that network professionals choose when the routing table gets serious.

The 16-Core Advantage — What Annapurna Labs Alpine v3 Delivers for Routing Performance

Processing Power That Changes the Conversation About What a Router Can Do

The central architecture of the CCR2116-12G-4S+ is the specification that defines its routing capability ceiling — and that ceiling is extraordinarily high. The Annapurna Labs Alpine v3 AL73400 processor delivers sixteen ARM Cortex-A72 cores running at 2.0 GHz — a processor architecture designed explicitly for network infrastructure applications, not adapted from a consumer computing platform.

Understanding why core count matters profoundly in routing hardware requires understanding how modern RouterOS processes network traffic. Unlike simple forwarding switches that operate purely in hardware silicon, a fully-featured router running complex firewall rules, dynamic routing protocols, VPN encryption, traffic shaping, connection tracking, and deep packet inspection requires substantial CPU resources for every packet that demands more than simple forwarding decisions. As routing complexity increases — more firewall rules, more VPN tunnels, more routing protocol peers, more queue trees — the demand on processing resources scales accordingly.

The 16-core architecture of the CCR2116-12G-4S+ addresses this reality directly:

RouterOS v7 is architected to distribute network processing workloads across multiple CPU cores simultaneously — with advanced features including Receive Side Scaling (RSS) and parallel packet processing enabling genuine multi-core utilisation across the full 16-core array. This means:

• 16 simultaneous packet processing streams capable of operating on different traffic flows concurrently without serialisation bottlenecks
• Routing protocol processing on dedicated cores — BGP table calculations, OSPF SPF runs, and MPLS label operations consuming cores that do not compete with fast-path packet forwarding
• VPN encryption on hardware-accelerated paths — IPsec offloaded to dedicated cryptographic engines rather than consuming general-purpose CPU cycles
• Firewall rule evaluation at high connection rates — the connection tracking table and stateful firewall engine running across cores that scale with traffic volume
• Traffic shaping and QoS processing — complex hierarchical queue trees executing without degrading forwarding throughput on other cores

The practical consequence: the CCR2116-12G-4S+ maintains routing performance that lesser hardware surrenders as complexity increases. Enable BGP with 1 million routes, add 50 IPsec tunnels, implement a complex firewall ruleset, and activate traffic shaping on all WAN interfaces — and the 16-core platform continues to route at throughputs that make those features feel invisible rather than expensive.

16GB DDR4 RAM — The Memory Foundation for Serious Routing

Why Memory Defines the Outer Boundary of What Your Router Can Achieve

In professional routing applications, RAM is not merely a comfort specification — it is a hard ceiling on routing capability. The 16GB DDR4 RAM of the CCR2116-12G-4S+ removes that ceiling from virtually every real-world deployment scenario this router will encounter:

Full Internet Routing Table Support The global BGP routing table currently contains over 900,000 IPv4 prefixes and a growing number of IPv6 routes. Maintaining a full internet routing table — necessary for ISPs, IX participants, and organisations with sophisticated traffic engineering requirements — demands substantial RAM for route storage, BGP attribute tracking, and RIB/FIB differentiation. The 16GB memory footprint of the CCR2116-12G-4S+ comfortably accommodates full internet routing tables from multiple BGP peers simultaneously — including multiple full tables with different path attributes for advanced traffic engineering without route summarisation compromises.

Large Firewall and Connection Tracking Tables RouterOS’s stateful firewall maintains an entry in the connection tracking table for every active network connection. In high-throughput environments serving many simultaneous users — particularly NAT-heavy deployments where many private addresses share public IPs — connection tracking tables can grow to millions of entries. 16GB RAM eliminates connection table overflow as a routing concern even in the most demanding high-user-count environments.

Complex Queue Tree and Traffic Shaping Structures Sophisticated traffic shaping implementations — hierarchical queue trees with per-subscriber queues, burst parameters, and priority configurations — consume memory proportional to their complexity and the number of simultaneous subscribers being shaped. For ISPs and managed service providers implementing per-customer bandwidth management, 16GB RAM provides the headroom for large-scale subscriber queue trees without memory pressure affecting routing stability.

RouterOS v7 Operating Environment RouterOS v7 introduces enhanced features including improved container support, advanced scripting capabilities, and expanded protocol implementations that benefit from generous memory availability. The 16GB allocation ensures RouterOS v7 operates with ample headroom for all features simultaneously without the memory pressure that triggers performance degradation or instability in memory-constrained routing platforms.

4 x 10G SFP+ Ports — High-Speed Connectivity for Backbone, Peering, and Uplink Applications

Ten Gigabits Per Port. Four Simultaneous High-Speed Paths. Complete Connectivity Flexibility.

The four dedicated 10-Gigabit SFP+ ports of the CCR2116-12G-4S+ are the connectivity tier that defines its capability as a high-performance routing platform — enabling 10G-speed connections to upstream providers, peering partners, core switching infrastructure, and high-bandwidth server resources that define the performance ceiling of your network:

Direct ISP and Carrier Uplinks Connect directly to carrier-grade 10G Ethernet handoffs from your upstream transit providers — eliminating the need for intermediate patch equipment and achieving the cleanest possible connection between your routing platform and your transit bandwidth. For organisations with 10G or multiple 10G transit circuits, the CCR2116-12G-4S+ terminates them directly on SFP+ ports while applying routing policy, traffic shaping, and firewall rules at line rate.

Internet Exchange (IX) Peering Connections Organisations participating in Internet Exchange Points — connecting to route servers and bilateral peers at IX fabric — benefit from the CCR2116-12G-4S+’s combination of 10G SFP+ connectivity, full BGP implementation with advanced path selection capabilities, and 16GB RAM accommodating large peer routing tables. The CCR2116 is engineered for IX peering deployments where routing sophistication and memory capacity are as important as raw throughput.

10G Fiber Uplinks for Campus and Enterprise Core Install MikroTik or compatible SFP+ SR/LR transceivers for 10-Gigabit connections to core distribution switches, campus backbone infrastructure, and data centre switching fabric — carrying routing and inter-VLAN traffic at 10G speeds between network tiers with complete RouterOS policy control over every traffic flow.

Direct Attach Copper (DAC) for Adjacent Equipment For high-speed connections within the same rack or between adjacent racks — to 10G core switches, server 10G NICs, or storage array controllers — 10G SFP+ DAC twinax cables provide cost-effective 10-Gigabit connectivity at distances up to 5-7 metres with minimal latency and zero optical transceiver cost.

LACP-Bonded 10G Uplinks Combine multiple SFP+ ports using IEEE 802.3ad Link Aggregation in RouterOS to create bonded logical uplinks — a 20 Gbps 2-port aggregate or 40 Gbps 4-port aggregate — with automatic load balancing and seamless failover if any individual 10G member link experiences a fault.

Dedicated High-Speed WAN and LAN Separation Utilise individual SFP+ ports as dedicated WAN-facing and LAN-facing interfaces — creating clean architectural separation between upstream provider connectivity and internal network distribution at 10G speed on each interface, with RouterOS firewall rules and routing policies enforced at the boundary.

12 x Gigabit Ethernet Ports — Versatile Connectivity for the Complete Network Topology

Twelve Ports of Full Gigabit Flexibility for Every Network Role

The 12 Gigabit Ethernet ports of the CCR2116-12G-4S+ provide the access layer and management connectivity that complements the 10G SFP+ uplinks — enabling flexible network topology implementations across a wide range of professional deployment scenarios:

Multi-WAN Load Balancing and Failover Terminate multiple Gigabit WAN connections from different upstream providers on dedicated GbE interfaces — implementing sophisticated multi-WAN load balancing with per-connection, per-address, or per-protocol traffic distribution policies, and automatic WAN failover with sub-second detection and recovery through RouterOS’s advanced routing and scripting capabilities.

Dedicated Management Interface Designate a dedicated Gigabit port for out-of-band router management — creating a separate management path that remains accessible even during WAN interface failures or routing table changes, with management traffic completely isolated from transit and customer data flows.

Segment and Zone Connectivity Connect separate network segments — office LAN, DMZ, server subnet, guest network, IoT zone, and management network — on individual Gigabit interfaces, with RouterOS firewall rules enforcing precise inter-zone traffic policies at line rate for each port combination.

LAN Switch Integration Connect aggregation switches, access layer switches, and distribution switching infrastructure via dedicated Gigabit interfaces — enabling clean router-on-a-stick or routed inter-VLAN architectures with RouterOS providing full Layer 3 routing, firewall, and traffic management between switching domains.

VLAN-Tagged Sub-Interface Architecture Each physical Gigabit interface supports multiple VLAN-tagged sub-interfaces — enabling a single physical port to carry dozens of logically separated traffic streams, dramatically increasing the effective interface count beyond the physical 12 ports for complex network segmentation requirements.

Hardware IPsec Acceleration — VPN Performance That Software Cannot Match

The VPN Capability That Makes the CCR2116-12G-4S+ a Data Centre-Grade VPN Gateway

For organisations where IPsec VPN performance is a critical infrastructure requirement — multi-site enterprise connectivity, remote workforce VPN gateway, carrier-grade VPN service delivery, or secure peering between data centre locations — the CCR2116-12G-4S+’s dedicated hardware IPsec acceleration represents a qualitative performance advantage over software-only VPN implementations.

Why Hardware IPsec Acceleration Changes the VPN Performance Equation

IPsec encryption operations — AES encryption and decryption, SHA authentication, and Diffie-Hellman key exchange — are computationally intensive processes that consume significant CPU cycles when implemented purely in software. On a router simultaneously managing large BGP routing tables, complex firewall rules, and traffic shaping, software IPsec encryption competes directly with these functions for the same CPU resources — creating a scenario where enabling IPsec at high throughput degrades overall routing performance.

Hardware IPsec acceleration removes this competition entirely by offloading cryptographic operations to dedicated silicon operating independently of the general-purpose CPU cores. The 16-core ARM processor handles routing decisions, firewall processing, and protocol management while the hardware crypto engine simultaneously processes IPsec encryption and decryption — enabling high-throughput IPsec VPN performance without any impact on routing, firewall, or traffic management functions.

Practical IPsec VPN Deployment Scenarios

• Multi-site enterprise VPN hub — terminate dozens of branch office IPsec tunnels simultaneously at high aggregate throughput without CPU saturation
• Remote access VPN gateway — support large numbers of concurrent IKEv2 remote access VPN sessions for mobile workforce connectivity
• Encrypted transit between data centres — 10G SFP+ interface IPsec encryption for secure high-speed inter-DC connectivity
• Service provider encrypted connectivity offerings — deliver IPsec-encrypted connectivity services to enterprise customers at line-rate throughput
• Secure peering encryption — encrypt BGP peering traffic over untrusted transport networks using IPsec without impacting routing table processing performance

Dual Power Supply Support — Operational Continuity for Mission-Critical Deployments

Redundancy Where Network Downtime Is Unacceptable

The CCR2116-12G-4S+ includes dual power supply slots — a hardware design decision that speaks directly to the deployment contexts this router is engineered to serve. When routing infrastructure fails, the consequences extend across every device, every user, and every service that depends on it. In ISP networks, enterprise environments, data centres, and managed service deployments where network availability is a contractual and operational requirement, single power supply routers represent an unacceptable single point of failure.

Dual PSU Architecture — How It Protects Your Network

• Single AC PSU included — the CCR2116-12G-4S+ ships with one power supply unit installed and operational
• Second PSU slot available — a second power supply unit can be installed to provide full hot-swap redundant power delivery
• Hot-swap capability — a failed PSU can be replaced while the router remains fully operational, with zero network disruption or routing session interruption
• Independent power path operation — each PSU connects to an independent power distribution circuit, protecting against single circuit breaker trip or PDU failure eliminating router power
• Automatic load sharing and failover — both PSUs share the router’s power load during normal operation, with automatic full-load assumption by the surviving PSU in the event of a failure

For ISPs, colocation facilities, enterprise data centres, and managed service providers where router uptime is measured in nines — 99.9%, 99.99%, or beyond — dual PSU support is not an optional luxury. It is a fundamental requirement that the CCR2116-12G-4S+ meets from its hardware foundation.

Q: What IPsec VPN throughput can the CCR2116-12G-4S+ achieve? The hardware-accelerated IPsec engine enables significantly higher VPN throughput than software-only implementations on equivalent hardware. Exact throughput depends on encryption algorithm selection, packet size distribution, and simultaneous feature load. MikroTik publishes performance benchmarks in their official documentation and community testing has demonstrated multi-gigabit IPsec throughput under AES-128 encryption — substantially higher than comparable-class software routing platforms without dedicated crypto hardware.

Q: What SFP+ transceivers are compatible with the four 10G uplink ports? The SFP+ ports accept standard 10-Gigabit SFP+ form factor transceivers — including MikroTik branded modules (S+85DLC03D for multi-mode fiber, S+1310DLC03D for single-mode fiber) and compatible third-party IEEE-compliant SFP+ transceivers. MikroTik’s SFP+ ports are generally compatible with standard 10G SFP+ modules from major vendors. Direct Attach Copper (DAC) cables are also supported for short-distance rack connections.

Q: Can the CCR2116-12G-4S+ function as a PPPoE concentrator for ISP subscriber management? Yes — this is one of the CCR2116’s primary ISP deployment use cases. RouterOS Level 6 licensing removes all PPPoE session count restrictions, while the 16-core processor and 16GB RAM provide the processing capacity and memory headroom for large-scale PPPoE subscriber management with per-subscriber traffic shaping, RADIUS integration for authentication and accounting, and dynamic bandwidth policy assignment.

Q: How is the CCR2116-12G-4S+ managed and what automation capabilities are available? The CCR2116-12G-4S+ is managed through WinBox (native GUI application), WebFig (browser-based interface), SSH CLI (command-line), and REST API (programmatic HTTP interface introduced in RouterOS v7). Automation integration is supported through the REST API, SSH-based scripting with tools like Ansible netmiko, NETCONF, and RouterOS’s built-in scripting language for on-device automation. Configuration backup and restoration is supported through CLI export commands and Dude integration for network-level monitoring.

Q: Is the second power supply slot populated in the standard CCR2116-12G-4S+ package? The standard CCR2116-12G-4S+ package includes one AC power supply unit installed. The second PSU slot is available for an optional additional power supply unit — available separately from MikroTik and its reseller network — for full hot-swap redundant power operation. Organisations requiring power redundancy from deployment day should order the appropriate additional PSU simultaneously with the router.

Q: How does RouterOS v7 differ from RouterOS v6 for CCR2116 deployments? RouterOS v7 delivers several significant advances relevant to CCR2116 deployments — including improved multi-core packet processing leveraging the 16-core architecture more effectively, native WireGuard VPN support, enhanced BGP implementation with RPKI support, REST API for modern automation integration, improved container support, and various feature enhancements across routing protocol implementations. The CCR2116-12G-4S+ ships with RouterOS v7 as its operating system, ensuring immediate access to the latest platform capabilities.

The Bottom Line — Why the MikroTik CCR2116-12G-4S+ Is the Professional Router That Changes What Your Network Can Achieve

The routing market is filled with products that promise performance and deliver limitations — limitations that reveal themselves when routing tables grow beyond a threshold, when VPN tunnel counts exceed a ceiling, when subscriber counts stress connection tracking memory, or when complex firewall rulesets finally find the boundary of what the CPU can sustain without degrading forwarding throughput.

The MikroTik CCR2116-12G-4S+ was not engineered to find those boundaries. It was engineered to place them so far beyond any realistic deployment requirement that they cease to be a consideration — replaced by a routing platform experience defined by consistent performance, feature depth without compromise, and hardware capability that matches the full ambition of RouterOS v7’s extraordinary software ecosystem.

Sixteen ARM Cortex-A72 cores that distribute packet processing, routing protocol management, VPN encryption, and traffic shaping across parallel processing streams without serialisation bottlenecks. Sixteen gigabytes of DDR4 RAM that accommodates full internet routing tables, large connection tracking databases, complex queue trees, and RouterOS v7’s complete operating environment simultaneously. Four 10-Gigabit SFP+ ports that connect your routing infrastructure to transit providers, peering partners, and core switching at the speed modern networks demand. Twelve Gigabit Ethernet ports providing complete multi-WAN, LAN, DMZ, and management interface flexibility. Hardware IPsec acceleration delivering VPN throughput that transforms encrypted connectivity from a performance compromise into a line-rate capability. And RouterOS Level 6 licensing that removes every artificial constraint from an already boundless software feature set.

This is the router that ISPs deploy for BGP. The router that enterprises deploy for IPsec. The router that MSPs deploy for multi-tenant VRF. The router that data centres deploy for edge routing. And the router that every serious network professional recognises as the most compelling combination of routing performance, feature depth, and investment value available in the professional networking market today.
