[j-nsp] Poll Question (VRF scale on MX)

[Sebastian Becker]

Hi Jason,

you’re right … the claims means that there is no (extra) software restriction besides what the hardware can deliver itself.

The MX204 should have the following scale limits:

FIB:		10M (IPv4 and IPv6 combined)
RIB:		80M (IPv4); 50M (IPv6)
VRFs:	6050

Mostly the given values are single scaled. So make sure you test that in a multiscale enviroment.

While I’m sure with that claim, RIB scale is limited to the amount of physical memory available on the box, I’m not sure what the physical limits are around the FIB.  My understanding is that it’s Trio Gen 3 based, but to that, I don’t actually know enough about the architecture yet to be sure.
