Hi,
I have created two scenarios. 1) with out Qos on L3 MPLS VPN and 2) with QOS configured. I have configured IP SLA to to test if QOS gives better out put for voice and video traffic as comare to without QOS scenario on GNS3. but i am getting opposit results.
I have attached the output collected with and with out QOS implemented. You can see the MOS value is higher in without QOS and Jitters are lower. I have attached IP SLA config also. During collecting stats I had run ping from R6 to R1 with size 1500 and repeat count 100000 to put some load on the link. I have uploded my GNS3 files on FTP and links are below.
You can download my GNS topology from below link.
IOS used (c7200-adventerprisek9-mz.124-24.T3)
