You brought antispoofing as an example, it's same thing, not everyone needs to do the right thing, anyone changing is better. And as I pointed out, the discussion isn't even 'how widely it works, if it doesn't work widely we shouldn't do it' that's illogical. Discussion should be 'should work, should we transit DSCP values as-is'. If you globally test (ring, ripe) how DSCP transits Internet, it's not horror story, it transit fairly well. We should not promote idea that you MUST reset DSCP at edge, we should promote idea you SHOULD tunnel your internal QoS, do not trust or modify external DSCP. I fully understand that some networks have no other recourse, they don't have overlay which to use QoS for, then they MUST reset DSCP as they MUST act on DSCP, that's entirely valid excuse. But networks which CAN transit it without caring about it, SHOULD do it, rather than assume they know how DSCP is used and should be used, they should assume they don't know and they're not going be the network which stops others from using DSCP. -- ++ytti _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
