Re: [swinog] Reset DSCP/IP-PREC field
Unless you have a contractual agreement with a peer/transit to honor their DSCP marking, you should always reset the value. Thomas Marcel Leuenberger wrote: 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?

RE: [swinog] Reset DSCP/IP-PREC field
Strongly recommended, unless the Provider's Backbone is DSCP transparent...
