> otherwise-unused router memory This makes it sound like a dynamic pool of memory which can be allocated for different purposes. I was talking about an ASIC where the amount of available memory for these state tables might be fixed and not available for sharing with other parts of the system. You get whatever the designers back in 2015 decided was needed and the point is there's not much reason for them to spend area implementing a bigger memory when the reality today is that it's hardly used. So I get what you are saying but it's not necessarily possible.
