[6bone] New version of ASPath-tree available on line.

[D'Albenzio Raffaele]

Hello Ronald,

no problem for your comments.

About the 100% unavailability of RIR allocated prefixes sometimes the
problem is because
there are some LIRs that asked to extend their prefix from /35 to /32
but they continue 
announcing /35.

>From ASPath-tree point of view in that case the real prefix it should
see is a /32. and
if the /32 is not present in the the routing table thant ASPath-tree
considers the sTLA 
unavailable.

Regards,
Raffaele.
