Hi Graham, I haven't personally tried this but do have plenty of hands-on experience with the MLXe platform. As far as I understood from previous conversations with my Brocade SE, if your firmware is recent enough and the card doesn't have any ports used in a certain VRF the selective FIB download will happen automatically.. you can verify this with the "show cam-partition usage" command. However, if you want to load a full Internet routing table while running a VRF-capable CAM profile you will need -X2 series linecards with the "cam-mode amod slot #" setting for ports which belong to the default VRF (e.g. the one which contains the 600k+ IPv4 prefixes). All the other cards whose FIB is going to be selectively populated may have -X, -M, or even -DM route table scalability. Best regards, Martijn Schmidt On 11/29/2016 03:19 PM, Graham Johnston wrote:

Does anybody have information on how to selective populate the IPv4 FIB on a Brocade MLXe?
