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 function by specifying as input a prefix for which BGP has reachability for, either via a BGP peer or a redistribute source.

Routing Control Functions (RCF) is a language that can be used to express route filtering and attribute modification logic in a powerful and programmatic fashion. This document covers Configurations of a RCF function for BGP points of application, CLI show commands to provide visibility into operational status, and the protocol attributes supported for BGP points of application.

In EOS, BGP creates different update groups based on the outbound configuration. Different route maps or Routing

This feature gives users the ability to use Route Control Functions (RCFs) to create custom policies for deciding which routes with IP next-hops should be programmed into the kernel with fwd* next-hop devices so the associated kernel packets are inserted into the ingress pipeline of hardware forwarding instead of being software-forwarded by the kernel.
