400G used to mean expensive, complex, and out of reach.
The CRS812 DDQ changes that!
With a modern Marvell switch chip and powerful ARM CPU, it
delivers advanced routing, switching, and traffic management
features trusted in millions of RouterOS deployments – now
with ports up to 400 Gbps!

• Campus core bridging 10G legacy with modern 50G
interfaces
• Service provider aggregation node
• Labs, AI clusters, media workflows where fast “eastwest” traffic is critical
The CRS812 scales your network from 10 to 400G in one

forklift upgrades needed!
