I would have classified the ISR 445x-X range of routers as hardware-based
routers, based on the different hardwares (both memory and
CPU/forwarding-engine) for control plane and data-plane.
On the other hand, I understood that the ISR 443x range are software-based
routers (same CPU/memory for

The ASR1000 is not a software router, in as far as FIB
programming is concerned.

Interesting your distinction because Cisco says that the 4451:
The product???s innovative hardware design splits the control and data
planes between two multi-core CPUs???
Indeed, that's where my definition would not trivially apply either way :-)
(And given how fast multipurpose CPUs

The ISR44xx series certainly is, with multi-core data plane forwarding,

Hello all
I’ve been googling during a long time trying to find the maximum route
table size of the Cisco ISR-4451-X but I can’t find it.
I would need a BGP full routing table and many internal routes (probably
more than 2.000). Bandwidth is not a problem, the estimation is about 500
tcam on asr1k is used just to filters/policies not to routing table, am I right?

ops, my bad.
TCAM seems used for routing in ASR1k too:
