Yes it will cost a bit more (router is more expensive than a LC)
I found the reverse to be true... chassis' are cheap. Line cards are costly.
Would like to hear what are your thoughts on this conundrum.
So this depends on where you want to deliver your service, and the function, in my opinion. If you are talking about an IP/MPLS-enabled Metro-E network, then having several, smaller routers spread across one or more rings is cheaper and more effective. If you are delivering services to large customers from within a data centre, large edge routers make more sense, particularly given the rising costs of co-location. If you are providing BNG services, it depends on how you want to balance ease of management vs. scale vs. cost. If you have the cash to spend, de-centralizing your BNG's across a region/city/country will give you more scale and better redundancy, but could be more costly depending on your per-box sizing as well as an increase in management time. If you want to improve management, you can have fewer boxes to cover large parts of your region/city/country. But this may mean buying a very large box to concentrate more users in fewer places. If you are trying to combine Enterprise, Service Provider and Consumer services in one chassis, well, as the saying goes, "If you are competitor, I approve of this message" :-). Mark.
