The figure below summarizes both the essence of the Cumulus Linux architecture as well as the philosophy that we use to guide our development.
Technology we innovated in-house to make your life easier:
Automation gets even easier with this simplified IP approach for BGP and OSPF. 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.
Efficiently go from whiteboard to physical cable. With PTM, you can program your data center to verify connections and resolve issues faster.
Run multiple network paths without the need for multiple switches, giving you traffic isolation and network segmentation for multiple devices.
Most advanced capabilities available for EVPN that allow legacy layer 2 applications to operate over next-generation layer 3 networks. Learn more about EVPN.
