[c-nsp] Enterprise IOS 12.2 default MPLS label protocol

I loaded 12.2(32) Enterprise since it listed MPLS VPN Support and its on a
Agg router with just T1's so I was trying to reduce some overhead and not
use SP code.  I can't get the MPLS VPN's to talk from this router.  I don't
see a way to change the label protocol (like with SP code below) and can't
find any docs on what the default is (the SP code mentions LDP is the
default but is that true for 12.2 Enterprise) ?   I am assuming that is my
problem at this point.  If I need to upgrade to SP code I can, but have a
few other Agg routers that I would like keep Enterprise running on.

Thanks
Eric
