MikroTik CCR2004 Deployment Case Study — Mid-Size Operator Core
A growing ISP needed to evolve from a single-site routing setup into a multi-site aggregation architecture. Their existing platform had sufficient port density, but was beginning to show CPU pressure under increasing BGP routes, firewall rules, and subscriber load.
They needed a routing refresh — not a full redesign, but a scalable core that could support current traffic while providing clear growth headroom.
The solution: deploying MikroTik CCR2004-1G-12S+2XS at each aggregation site, paired with RB series devices at the edge.
Why CCR2004
- ARM64 quad-core CPU — improved efficiency and lower power consumption compared to older Tilera-based platforms
- 12x SFP+ 10G ports for high-density aggregation
- 2x 25G SFP28 uplinks for high-speed inter-site connectivity
- RouterOS v7 with full BGP, OSPF, and MPLS feature support
- Designed for high-throughput routing workloads in compact form factor
The topology
- CCR2004 at each site — BGP peering with upstream providers, OSPF for internal routing between nodes
- WireGuard tunnels for secure management traffic
- FastTrack used selectively to optimise established flows
- RB series deployed at edge for cost-efficient subscriber aggregation
Outcome
The deployment achieved stable multi-site routing with sustained high inter-site throughput under production traffic conditions. Management was simplified through reusable RouterOS configuration templates, while power consumption remained suitable for colocation environments with strict power budgets.
Not every operator requires a high-density chassis platform. The CCR2004 provides a balanced routing core that bridges performance, density, and efficiency for mid-scale ISP growth.
We carry the full MikroTik lineup and support SI/operator deployments from design through to commissioning.
