IMHO, wasting any resource is unfortunate, but the cost of additional forwarding table entries far outstrips the cost of additional DRAM. Thus, adding an additional prefix does merit a significant shout from others, but the stub AS should only be an incremental whimper.

It's not just the amount of resources spent, it's what you get for them.

Spending a little on nothing is worse than spending more on something useful.

Personally, I think a prefix which gives routability info is useful. A Stub AS is just a waste.


P.S. This also means a /24 with the same AS path as the enclosing /16 is also a waste - an even bigger one.
