I have an issue between a Cisco 6500 and 7206VXR. We are marking incoming traffic with DSCP(5 and 2) at the border and shaping based on the values on the 7200.
Most traffic seems to be coming through with a DSCP 0. Even though it is being marked at the border and working on other 6500s. It is only the 7200s that are having the issue. I have placed an access list on the core interface of the 7200 to confirm traffic is coming through as DSCP 0.
We use dscp 5 for international and dscp 2 for domestic. This used to work when we had 7500s marking the traffic, but broke once the 6500s went in. We are also running MPLS across the core.
