I have implemented RFC 2096 once on a very simple end system.
While I concede that it was a big improvement over the broken
ipRouteTable in RFC 1213, I could not help but think while
writing the code how difficult it would have been to implement
efficiently in any kind of complex equipment.
Based on that experience, I tend to believe that a major
restructuring is probably necessary if you want something
that is both logically consistent and reasonably efficient
to implement. I don't think that a simple restructuring
of RFC 2096 to be IP version-neutral will gather much
support among implementors.
At the very least, I would urge that you ask for deployment
reports for RFC 2096 before deciding that a simple
version-neutral update is the right way to go.
