Juniper, Cisco IOS, IOS-XR and NX-OS all support it.  RX support in quagga is done but isn't in a released version of quagga yet, TX support in quagga is on our roadmap.  Bird added addpath support recently.

Not sure about Arista.

Jeff and Acee:

The revision of the add-paths work is good news.  

To WG: 

Will anyone who has knowledge of the implementations of this draft on
add-path please either post the information to the mail-list or send the
information to the John Scudder and myself?

The update below addressed the major open issue that remained for the
feature, as deployed, to match the spec: The behavior for ebgp has been
moved out of operation and into deployment considerations.

I'm not an author, but I believe this draft is finally read for a hopefully
short Working Group Last Call.
