Unfortunately our AUP doesn't allow warning you for having no idea what 
you are talking about. But I'd like to point it out anyhow.

"most backbone routers build circuits at the /18 and above mask on MPLS,
just to keep up with traffic" is, erm, wrong. backbone routers don't build 
circuits. they don't mask on mpls either. (how do you even mask on MPLS?)

More serious reply is on-list.
