The HW has exactly same 256MB RLDRAM as rest of Juniper high-end gear,
including T4k. I.e. FIB is identical in all MX and new trio generation T
gear.

You can see how that memory is spread and populated via 'start shell pfe
network tfeb0' and 'show jnh 0 pool ...'

Any number would be only indicative/marketing. Much as same as if you'd ask
how many routes can your laptop handle, it would depend what else will be
using the memory.
I'd say 1M is reasonable figure, maybe in some environments you could push
it to 1.5M but you'll certainly not going to see 2M.

I worry about this bit, as I already have boxes with >800k IPv4 prefixes.
