Stale routes are learned routes from adjacent BGP neighbors whose neighborship has been interrupted by session instability. This feature adds a mechanism to specify a stale policy route-map for which the stale routes from a gracefully restarting, or depending on the configuration of the feature, a non-gracefully restarting BGP peer will be processed.

BGP VPN routes today advertise a label by dynamically allocating it from a dynamic label range block without providing the user any control over the label value that is allocated per VRF’s address Family - VPNv4 or VPNv6. This feature allows the user to configure a unique label per VRF’s configured address-family, VPNv4 or VPNv6, thereby allowing the user granular control over the label value advertised with VPN routes exported from a VRF.

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 enables the user to configure a list or range of BGP attributes to be ignored by the router on receipt of a BGP update message. The BGP attributes are discarded from the BGP update message, and unless the action of discarding an attribute causes the update message to trigger error handling, then the update message is parsed as normal.

EOS supported two routing protocol implementations: multi-agent and ribd. The ribd routing protocol model is removed starting from the EOS-4.32.0F release. Multi-agent will be the only routing protocol model. Both models largely work the same way though there are subtle differences.

This document describes a new CLI command to help debug how and why policy permits and denies paths. The aim of this CLI command is for the user to debug a route map or RCF (Routing Control Functions) function by specifying as input a prefix for which BGP has reachability for, either via a BGP peer or a redistribute source.
