We are thinking of building an enterpise MPLS backbone consisting of about 30 7206 Vxr routers. This deployement would have basic MPLS L3 capabilities, Vrf -Multicast aware, and support customer QOS.
My question is what code should we be running. Should we be running 12.0 code or 12.4 code based on the features. I see some providers are running 12.0(22)s code. Is there any advantage of running 12.4 if yes what version?
