Y'all:

I know this is in auth-48 (or maybe past), but I've been through these docs
a number of times, and still come up with questions that I think need to be
addressed/answered at some point. In general, eVPN seems to be on the
receiving end of "I can imagine a lot of different use cases, some of which

In step 3 of DF election, the list of IP addresses is ordered in "increasing
numeric value." What if you have a mix of v4 and v6 addresses?

[Satya] One possible solution may be to do a lexicographic comparison of keys 
(the iP address strings in this case considered as sequence of bytes).
For unequal-length keys like in the case of v4 and v6, assume that a unique 
'padding' alphabet is present after the v4 address that always has priority  
over other alphabets (byte values).
This will make the comparison non-ambiguous, and still the same algorithm 
suffices.
