Davor,

The datasheet refers to 1024 VRFs with 700 routes each (tested numbers) but this is just an example as you could, in principal, have any combination of # VRFs * routes/VRF that would equal 700K routes (i.e. 2 VRF * 350K routes or 1 VRF * 700K routes).

I say in principal because I have never seen a customer requesting the support for that many routes and have never tested it either.

Hope this helps,
