It is pretty clear that this 6bone rule is in serious contradiction
with bgp4 paradigm and with concept of AS numbers. Read, with reality 8)

Probably, I do not understand something, but it is impossible
to inhibit exporting shorter prefixes without getting rid of
these concepts.

Suppose, my pTLA is collection of 3 AS. 2 of them have tunnels.
If I do aggregation, it will not only make paths much longer,
I will be forced to export aggregate with different AS paths!!!

I am sorry, I prefer to violate any rules, only to avoid BGP breaking.
