When Michnet border router advertises a route for a destination in UMnet, does it use the ASPath "MichnetASno UMnetASno" or just "MichnetASno" or "UMnetASno"? (Perhaps UMnetASno = MichnetASno?). If it uses "MichnetASno", implementing policies at the AS level would not work. (Problem is at bad IGP-BGP interaction not becuase AS level policy implementation is inadequate.) Does this kind of IGP-BGP interaction happen in lots of places? Thanks.
