Wired router MikroTik CCR2116-12G-4S+ — 13x Gigabit RJ-45, 4x SFP+, 2000 MHz, DDR4, white

The MikroTik CCR2116-12G-4S+ is a wired router built for high-throughput environments, combining Gigabit Ethernet interfaces with a modern multi-core 2.0 GHz Alpine CPU. With 16 cores and Layer 3 hardware offloading support, it delivers improved single-core performance for connection-oriented tasks while offering 12 Gigabit LAN ports, one additional CPU-connected Gigabit management port and four 10G SFP+ ports for high-speed uplinks. The device includes a dual-redundant power supply option and typical power consumption around 72 W, suitable for ISP and enterprise deployments requiring stable 10G connectivity and long-term reliability.

Advantages

The CCR2116-12G-4S+ provides strong per-connection processing due to its 16-core Amazon Annapurna Labs Alpine CPU and shows measurable single-core gains compared with previous models. Four dedicated 10G SFP+ ports and thirteen Gigabit Ethernet interfaces (12 via the Marvell switch chip and one CPU-connected port for management) reduce bottlenecks by giving each group of ports a full-duplex line to the switch chip. Hardware Layer 3 offloading and a design focused on high throughput make it appropriate for complex routing, firewall and QoS tasks while maintaining efficient power use and reliability.

Suitable for

• Large ISPs handling dynamic routing and massive BGP sessions
• Enterprises requiring high-throughput 10G uplinks and many Gigabit edge ports
• Networks with complex firewall rules, queues and per-connection processing
• Environments needing redundant power and long MTBF for continuous operation

Key specifications

• CPU: Amazon Annapurna Labs Alpine, 16 cores, 2.0 GHz
• Ethernet ports: 13 x Gigabit Ethernet (12 via Marvell switch chip + 1 CPU-connected)
• 10G ports: 4 x SFP+
• Layer 3: Hardware offloading supported
• Power consumption: typical 72 W
• AC input: 100 - 240 V
• Color: White
• MTBF: 200,000 hours

How to use

Install the CCR2116-12G-4S+ in a standard rack or on a stable surface, connect the four 10G SFP+ modules or cables to your uplinks and plug Gigabit devices into the RJ-45 ports. Use the dedicated CPU-connected Gigabit port for management access to configure routing, firewall rules and QoS in RouterOS. Enable Layer 3 hardware offloading where applicable to reduce CPU load for routed traffic. Configure redundant power inputs if continuous uptime is required.

Recommendations

For optimal performance in ISP or enterprise environments, place high-bandwidth flows on the 10G SFP+ uplinks, keep per-connection heavy processing (for example deep packet inspection) to a minimum where possible or distribute tasks across multiple devices, and use hardware offloading features to maximize throughput and single-core efficiency.
