I have a remote building that has about 60 users. We are getting a layer 2 MPLS (opt-e-man) service point to point. I plan to have 2 network at the remote site 1 for data and 1 for voice. There are other vlans I need there for authorization as well as access points. What would be the pros and cons of layer 2 vs. layer 3 connection? Is a mpls tunnel secure (meets pci and hippa requirements)? I am running 3750 class switches and have routers and ASA to use if need.
Thanks for your imput.
