It's not only allowed but recommended ;-)

HiYa!

Just want to ask you if it is "allowed" to reset the IP-PRECEDENCE/DSCP-Field to
Zero (or any other value) at the border of an ISP network?
Means there is no problem if an IP-Transit provider reset the customers
IP-PREC/DSCP field because INTERNET is best effort and therefore each ISP can do
with the IP-PREC/DSCP whatever he want's because each ISP has it's own
"QoS-Domain and rules"?

For me resetting the IP-PREC/DSCP is a must concerning security and to declare
Internet-Traffic as BE in internal networks.

Or I am wrong and are there any existing rules in the "ISP" community relating
modifying IP-PREC/DSCP?

Are you resetting the IP-PREC/DSCP as well?

Thanks and greetings,
- Marcel
