For a requirement we need to configure multiple vrf's on a customer premise equipment basically to extend the VRF from the MPLS cloud till the CPE. I would like to know on the scalability of such a solution. How many vrf's can i create on a CPE and how will it effect the CPU & Memory of a router. I am talking of vrf-lite. Need to know on the router capability for Cisco 3825, 3845 & 7206 routers.
