Choosing between a CCR (Cloud Core Router) and a MikroTik CRS (Cloud Router Switch) for layer 3 depends on several factors, such as the required performance, the specific characteristics of the network and the available budget.

We give you the key considerations to help you make an informed decision:

Performance and Capabilities

• CCR: CCR devices are specifically designed to offer high routing performance and advanced Layer 3 functions. They offer significantly greater packet processing capabilities and are suitable for large-scale networks that require high performance and scalability.
• CRS: CRS devices, although they can also perform Layer 3 routing, are primarily optimized for Layer 2 switching functions and may have slightly lower performance compared to CCR devices. They are best suited for environments where switching is the primary function and routing is less demanding in terms of performance.

Features and Flexibility

• CCR: CCR devices typically offer a wide range of advanced features and functionality, such as dynamic routing, VPN, firewall, QoS, and more. They are ideal for deployments that require a full set of routing and security features.
• CRS: While CRS devices can also support some advanced routing features, their primary focus is on switching functions. They are best suited for environments where you primarily need Layer 2 switching with some basic routing capabilities.

Cost

• CCR: CCR devices tend to be more expensive compared to CRS due to their higher processing capacity and richer feature set.
• CRS: CRS devices are typically more economical and offer excellent value for money for environments where a combination of Layer 3 switching and routing is needed at a lower cost.

Usage Scenario

• CCR: CCR is recommended for use in environments where high performance, scalability, and advanced routing and security capabilities are required, such as service providers, large-scale enterprise networks, or data centers.
• CRS: CRS devices are ideal for small and medium-sized businesses, branch offices, home networks, and environments where Layer 2 switching is the primary function, but basic routing capability is still needed.

In summary, the choice between a CCR and a MikroTik CRS for layer 3 will depend on the specific performance, functionality, cost and usage scenario needs of your network. It is important to carefully evaluate your requirements before making a decision.
