Sorry I fail to understand this. Could you elaborate with an example?
Let's assume I'm AS1 and 2.0.0.0/16 from AS2 is sending me DSCP CS5, which I
don't want to honor. And 2.1.0.0/16 from AS2 is sending me DSCP CS5, which I
want to honor.
How in practice should I honour 2.0.0.0/16 to every destination in my network
and never honor from 2.1.0.0/16 to any of destinations in my network? My
margins unfortunately don't permit building two paths to each directions.
