> The very first page of the Intro document says that RLOCs and EIDs can be syntactically different from IP addresses. However, it leaves the reader to guess what this means. So, I need to ask 20 seemingly obvious questions to ferret out the actually meaning. Believe me, it is as painful to me as it is to you!


But it's not as complex as you may think it is.

> What does it mean to be "syntactically different" from an IP address? If you can explain that, we won't have to play 20 questions.

It means the EIDs and RLOCs can be from any address family. 

Syntactically an AppleTalk address is different than an IPv4 address.
