What network challenge are you facing?
What you get with Cumulus Linux
Technology we innovated in-house to make your life easier:
Create configs faster by no longer depending on unique IP addresses, which simplifies automation.
Automation gets even easier with this simplified IP approach. All you need is one IP template for leaf nodes and one for the spine nodes. Easy, right?
Get VM and host mobility by plugging in your server into any RDNBR switch making it L3 discoverable on the fabric. If you have any need to move the server, there’s no need to reconfigure.
Prescriptive Topology Manager (PTM)
Efficiently go from whiteboard to physical cable. With PTM, you can program your data center to verify connections and resolve issues faster.
Virtual Routing and Forwarding
Run multiple network paths without the need for multiple switches, giving you traffic isolation and network segmentation for multiple devices.
Lightweight Network Virtualization (LNV)
Accelerate VXLAN deployments with a controllerless solution.
Ethernet Virtual Private Networks (EVPN)
Get freedom from L2 complexities with this modern, standards-based, interoperable technology that allows legacy layer 2 applications to operate over next-generation Layer 3 networks. Learn more about EVPN.
