I'd go with a Nokia/ALu 7750. Two 48x1G IMM, or 5x m20-1gb-xp-sfp MDA
+ 3 IOM3-XP, and 100G IMMs (1 or 2 CFP ports - no idea about qsfp28
options though) with SF/CPM5. This would fit in a SR7. Not sure about
the smaller models (-c or -a series). The 7450 might be an option too,
but I don't know this hardware.

RIB size is 20M iirc (shared between all af) and fib size 3 or 5M
depending of the card. SR-OS is weird when you're used to ios or
junos, but in the end the cli is very efficient and quite enjoyable
actually.

HTH,
pierre
