Again, you are under no obligation to do anything with QoS flags from
non-paying customers, and I'm not advocating for anybody to get a free
ride here. Ignore the markings, but leave them alone too.
Yes please. HOW? That is what I have been asking since the first post -
how do you suggest honoring DSCP for paying customers AND ignoring them
for non-paying customers (while leaving them alone) - WITHOUT putting the
traffic onto "dedicated" networks (be it L2 or L3)? If you can answer that
single question I'll shut up and run along to implement it. (And keep in
mind not all providers have a full MPLS core, so let's stick to normal IP
forwarding please).
