With QPPB, you don't, with QPPB while processing the BGP NLRI, based
on community or whatever information you have in RIB you assign QoS
class. This is then given to the FIB and will be part of the lookup
process, when DADDR is looked up, it will get rewrite information and
QoS class information.

So your BGP community could be 65000:fuckup, 65000:fuckup5mbps and so
forth (of course some number representing fuckup). Then when you
originate those prefixes, you need to attach the right community to
them. But you don't touch the QoS config on the far end, that would be
done automatically based on the community.

If you must push new ACL on the device then this is more question of
automation. Your options would be screenscraping or netconf.
