I currenlty have a Cisco 3750 in my datacentre which has a trunk port to a provider allowing certain VLAN's over (This is my A end) the B end's are encapsualated onto Cisco 2800's (this is a hub and Spoke setup). Now I have multiple VLAN's on my 3750 at Layer 3 for each VLAN that comes over the trunk as I run a dynamic routing protocol with the B end sites. What I have been asked to do is mark certain traffic on the B end and the A end. I can do this easily on the B end but I am unsure how it will work on the A end ( I need to mark VOIP and Cirtix). Can it be done with this setup on the 3750 with this setup?
Any questions or thoughts please let me know.
