The designers of Cumulus Linux CLI were always focused on simplifying network device configurations. One of the first features along these lines was BGP across unnumbered interfaces, then they introduced simplified EVPN configurations, and recently auto-MLAG and auto-BGP.

You can watch a short description of these features by Dinesh Dutt and Pete Lumbis in Simplify Network Configuration with Cumulus Linux and Smart Datacenter Defaults videos (part of Cumulus Linux section of Data Center Fabrics webinar).
