That's right, logic is in programming chips, not their property. You just need to know what to program ;-)

Juniper/Cisco support it using policies to filter RIB->FIB and I believe both also do per-NPU/PFE localized FIBs now. I am not sure if that’s something supported on this new Broadcom chipset.  Depends on your network of course and where you are looking to position the router.
