Not necessary but it should ...

Now you are speaking.  That is the problem  though I don't know why.
other politics, I meant policies.
We have similar problems.  some of our block is annouced one way and
another block  are annouced other way though we are not doing anything
 really special.  What makes even worse that though for some BGP path 
is annouced but because of filtering, it is not really a path. :~<

I can almost bet that someone on  your AS_PATH knows  what is going on
your BGP annoucement. One of the way to solve the problem is ask everyone 
on AS_Path to see anyone is really doing something.  
That's I am intend to do for my case.

Any better idea?
