I've got what will probably sound like a stupid QOS question, but I can't come up with something I'm confident is the 'right' answer.
Let's say I've got this setup R2 g0/0 -> g0/0 R1 g0/1 -> BB1 ...and then there's a serial connection from R1 to R3 And what I'm told is that any traffic coming from BB1 and destined for R2 networks should be marked with DSCP13 and traffic from BB1 networks destined for R3 should be set for DSCP EF. Because traffic from other directions could end up going through R1 to R2 and R3 I can't just setup an outgoing policies on the relevant interfaces to mark the DSCP. IIRC, last time I messed with this I couldn't tag the incoming traffic as originating from BB1 and then match that tag outgoing on the various interfaces to set the DSCP. The two ways it seems to me that this could work would be... 1. Mark the QOS on the stuff incoming from BB1 at an arbitrary value, match that arbitrary value on the way out, and then set the correct value or 2. Looking at the subnets coming from BB1, use those as your match clauses on the R1 outgoing interfaces and use those to set the DSCP. Now, number one up there seems risky because it's assuming you know all DSCP values and your arbitrary value could potentially step on them. Plus, you're setting values you weren't told to. Number two, which I'm guessing would be the "correct" answer seems to be a matter of making some huge ass assumptions. Are there more ways that anyone can suggest? What's the "correct" answer? _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com Are you a CCNP or CCIE and looking for a job?
