Well, there is not a strict algorithm, it depends on memory and CPU
which depends on # of routes/vrf, #vrfs, #interfaces and routing
protocols configured on these VRFs.. Ballpark figure to work with is
>500 VRFs, but it can also go much higher (or lower if you have lots of
interfaces with RIP running with low timers on all of them ;-)..
