The Cisco 3800, 2800, 1800, 870, 3700, 2600, and 1700 Series provide Multi-VRF customer edge support. No tagging or label distribution is involved, but the physical router supports multiple VRFs. Recommended positioning limits for throughput and the number of VRFs scale from 2 Mbps and 2 VRFs on the Cisco 870 Series, and up to 45 Mbps and 25 VRFs on the Cisco 3845 Integrated Services Router.
