Thanks Kevin for your suggestion. The topology being tested is the following:
R7 Eth R5(hub) FR R2 and R1 (Spokes)
I'm pinging R1 from R7. R2 is PBRouting accordingly but not marking precedence 3. It is writing COS 3 only when the destination of my pings is R2.
Best regards
DB

Maybe the switch in between is rewriting the COS ...
Just a thought.
