You could Zebra peer with the Bogon route-servers and accept

This works fine if you can remember to keep your bogon filters current,
which we and other networks in oz have found recently many networks in
fact do not.

Which reminds me, if anyone has 125.0.0.0/8 null routed, shame on you :)
It was brought into life many months ago by APNIC.


Cheers
