> To put an even finer point on it, one of the big problems with EIGRP at this point is that although that are many interoperating implementations, they were implemented using a reference implementation, not a spec, so there is no spec that got the kind of interop testing that multiple independent implementations would have given us. Getting to that now would be very difficult, since there's no real incentive for anybody to do a complete new implementation now.  So while indeed it might be good to write down the spec for posterity and the benefit of sharing experience, I don't think it'd make a lot of sense as an IETF standard.

My point on RFC 6126 is that it’s not an IETF standard either, yet homenet appears to be deciding to standardize on it.

I don’t know the status of Donnie Savage’s draft (https://datatracker.ietf.org/doc/draft-savage-eigrp/). However, the EIGRP data formats are well known, the algorithms are well known, and if the vector metric patent and the DUAL patent haven’t expired, they're about to. As you say, there are multiple implementations around. What I’m looking at is a request for commentary in a draft making comments on the operational use of routing protocols.
