## What You Get with Cumulus Linux
### Key Features
 * **Unnumbered Interfaces** : Automation gets even easier with this simplified Internet Protocol \(IP\) approach for Border Gateway Protocol \(BGP\) and Open Shortest Path First \(OSPF\). All you need is one IP template for leaf nodes and one for spine nodes.

 * **Redistribute Neighbor \(RDNBR\)** : Get virtual machine \(VM\) and host mobility by plugging your server into any RDNBR switch and making it layer-3 discoverable on the fabric. If you 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.

 * **Ethernet Virtual Private Networks \(EVPN\)** : The most advanced capabilities available for EVPN allow legacy layer-2 applications to operate over next-generation layer-3 networks.

 * **NVIDIA User Experience \(NVUE\)** : A full command-line interface \(CLI\) object model of Cumulus Linux enables advanced programmability, extensibility, and usability.

 * **Digital twins** : [NVIDIA Air](https://air.nvidia.com) makes physical deployments seamless by validating and simplifying deployments and upgrades in a virtual network.
### Standard Technology—with Improvements
 * **Disaggregation** : The open architecture using a Linux operating model unlocks the stack.

 * **Native Security** : From OpenSSH to authentication, Cumulus Linux keeps your switches secure.
 * **Unified stack** : With a unified operating model across compute and network, you'll reduce complexities and get guaranteed interoperability.
 * **Software Driven** : Our software writes directly to the silicon, giving you a software-driven and hardware-accelerated approach.
