I'd have to agree.

Enabling MPLS for its own sake isn't terribly useful. The 
initial concept of its development (faster forwarding) was 
novel, but times changed real quick, to put it mildly :-).

The only reason we've "probably" seen to enable MPLS without 
any of the advanced features is to remove IPv4 BGP routes 
from the core, if that is something anyone can find useful. 
But remember, you'd still need those routes at the edge so 
that FEC's can be created (LDP) to allow forwarding in an 
otherwise unintelligent core.

Other than that, and in the absence of typical MPLS-based 
applications, not much use to turn it up.

Cheers,

Mark.
