Right as is MX304.
I don't think this is 'my definition', everything was centralised
originally, until Cisco7500 came out, which then had distributed
forwarding capabilities.
Now does centralisation truly mean BOM benefit to vendors? Probably
not, but it

Right as is

This of course makes it more redundant than distributed box, because
distributed boxes don't have NPU redundancy.
Well, by your definition, the ASR9903, for example, is a distributed

In this context, these are all distributed platforms, they have
multiple NPUs and fabric. Centralised has a single forwarding chip,
and significantly more ports than bandwidth.
So to clarify your definition of "centralized", even if there is no

I agree that using vendor satellites solves this problem. The issue,
IIRC, is was what happens when you need to have the satellites in rings?

Yes. Satellite is basically VLAN aggregation, but a little bit less

Apart from obvious stuff like QoS getting difficult, not full feature
