Strongly recommended, unless the Provider's Backbone is DSCP transparent...

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?
