1) All routing data must be present at the RIPE DB. If you work with 
RIPE DB you could see that webtools don't allow you to create route to 
ASN not from RIPE region.
2) RIPE IP Usage policy don't allow to route RIPE IPs from non-RIPE region.

IPs are announced by Level3... I respect this company but looks like 
Level3 is scammed and currently announce without necessary permissions.
