We struggled with a number of networks using these over eBGP sessions
they had with networks that shared their routing data with BGPmon. It
sent off all sorts of alarms, and troubleshooting it was hard when a
network thinks you are de-aggregating massively, and yet you know you
aren't.

Each case took nearly 3 weeks to figure out.

BGP optimizers are the bane of my existence.
