I checked  at http://bgpupdates.potaroo.net/cgi-bin/per-as?as=29571  and saw

It looks like you have tried to do something  using the ASPATH prepend and is  
not happy  with the results.

As your three lines are going into the same AS, there are  a lot of incoming 
traffic engineering stuffs you could  do  with and inside AS5511.

on the side of your announces aggregation, the link above has some suggestions 
for you.
