There is control over both in RSX as well, but there NICE isn't reporting the buffer size in that parameter, but you can see it in another place, and yes, it's the value used in the routing advertising, which makes sense, since that is what you announce you will accept as size for routing packets. And yes, it's (completely) unrelated to the segment buffer size, which is what NSP cares about. And as long as the buffer size is atleast large enough to hold the maximum segment size, everything will be happy. I also haven't checked any code, but for ethernet, I would think that routers will either send out 1500 byte packets, or send out the packet the size of the smallest announced accepted size. Now I'm sortof curious which. Maybe the DECnet routing spec already would tell me... I know that for point-to-point links, RSX sends packets larger than the segment size if routing init says it can accept that, as long as the sending side can build that size.
