Hello Justin.

Yes, there is running code. The Internet-Draft that eventually became RFC 7298 was written at the same time as the code was developed, you can find it in this git repository: https://github.com/Quagga-RE/quagga-RE

Specifically, the commits are listed on this wiki page (rounds 5 and 6): https://github.com/Quagga-RE/quagga-RE/wiki/hashes

As far as software licences go, this was a GPL contribution to a GPL software if that helps. I don't remember when I ran this code last time, unfortunately. When it was developed in 2012-2014, it was working fine. If you want to debug it on wire, tcpdump can print the TLVs from RFC 7298.
