Harald,
My understanding (seen from a VERY long distance) is that the routing
scaling problems are substantially the same for both dialects
of IP,
Correct.
and that initial efforts have focused on encapsulating either,
with the initial experiments using IPv4 as the encapsulating
protocol.
Is this understanding correct?
Close. First, no formal experiments have been defined in
the WG context (to the best of my knowledge).
Next, we have 4-to-4-over-6 (464), 6-to-6-over-4 (646),
4-to-4-over-4 (444) and 6-to-6-over-6 spec'ed and running
in the field, so any combination of those is available for
experimentation. Of course, any X6X (for X = 4 or 6)
requires a 6 path between xTRs.
