Tony,

What architecture?
PBR is a form of:
match DSCP X
set next-hop Y
needs no interoperability...
If someone wants to describe how they use a particular vendor feature to
solve a particular problem in a BCP, sure, the more BCPs - the better.

Wrt using DSCP in routing decision process - it was a bad idea back then,
hasn’t got any better now... besides - now we have got a toolbox that
wasn’t available then.

Cheers,
Jeff
