FWIW, if you don't announce your aggregate, do not be surprised if you
experience continued disconnectivity to many parts of the Internet. Some
SPs notice that SoftbankBB have received 126/8, so will likely filter as
such. Leaking sub-prefixes may be fine for traffic engineering, but this
generally only works best if you include a covering aggregate.

Try including your /8 announcement and see if this improves reachability
for you.

Out of curiosity, why pick on a /16 for traffic engineering? Most people
tend to analyse traffic flows and pick the appropriate address space
size as a subdivision. Or do you have 256 links to upstream ISPs and
need that level of fine-tuning?
