Good morning list, I have a 6500 (720-3c, 6716) functioning as a PE, and have a QOS question regarding its label imposition process. 1) Will a packet entering via a SVI in a VRF (MPLS L3 VPN) have its IP PREC bits automagically copied into the MPLS-EXP bits, or do I need to apply an ingress policy map on every PE-CE interface & SVI translating IP-PREC/DSCP to MPLS-EXP? It´s automatically copied. Nothing to worry about. 2) Do I need to configure "mls qos trust dscp" on the PE-CE ingress SVI in a VRF? Or just the switchport? Or Both? Just the switchport. 3) Do I need to configure "mls qos trust something" on the PE-P interfaces so that MPLS-EXP is respected and not stripped off? Only if it's used L2 switchport. I don't currently use any L2 or L3 QOS on the 6500, and just want the IP PREC bits marked and passed upstream to the P routers for prioritization in the core. Thanks! _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
