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.

With the DANZ Monitoring Fabric (DMF) 8.7 release, a DMF Controller will allow sharing of managed services utilizing L3 delivery interfaces (e.g., NetFlow, IPFIX, app ID, etc.) across multiple policies. In prior releases, DMF did not support managed service sharing because the L3 delivery interface was an optional setting in a policy configuration. However, sharing is now supported because the managed service configuration must now specify the L3 delivery interface.

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.

This feature enables policer (using policy-map) on a VTEP to rate limit traffic per VLAN/VNI. The policer can be applied in both input and output directions to rate limit decapsulated and encapsulated VXLAN traffic, respectively. Prior to EOS-4.32.0F, the policers are not applicable on multicast traffic through the VTEP. For platforms supporting rate limiting of both bridged and routed encapsulated traffic, the rate limiting would be done on common policer limits.
