Erik,

>On the Cisco 12k prp-2 there is a IPv4 Address limit of 1Million routes.

please note that you also need to take the individual linecards' FIB
capability into account as this is where the routes are stored..

> Is there an limit on the number of VRF's that you are able to have?

This also depends on the number of routes per vrf and features enabled per
vrf (pe-ce routing protocol), simple setups can scale to ~700 VRFs in IOS
and more than a 1000 in IOS-XR on the 12k platform..
How many do you need?
