The “maximum-paths <m>” (default m=1) configuration that controls BGP’s multipath behavior, is available as a global knob, and not as a peer/peer-group knob today in EOS. When “maximum-paths” CLI is configured with m > 1, BGP starts forming ECMP groups for paths with similar attributes received from all configured neighbors.

Routing control functions (RCF) is a new language, a different way of policy definition and application in a programmatic fashion (https://www.arista.com/en/support/toi/eos-4-27-2f/15102-routing-control-functions-language-and-configuration). EOS Application Programmable Interface (eAPI) is another means whereby commands are sent to the switch (i.e. aside from the switch’s command-line interface - CLI which has been the norm), which can be executed through various methods like web interface, shell or a program/script.

This feature adds support for specifying Resolution Rib Profile as system-connected per-via (next-hop) for static routes. System-connected means that a static route is only resolved if the next-hop is reachable over a connected route. If system-connected is not specified, it means that the static route is resolved if the next-hop is reachable over any kind of route in the routing FIB, including a connected route as well as a tunnel rib.
