[c-nsp] 3750 Metro MPLS

Be aware that MPLS support in 3750ME is a mess, with lots of
limitations, unsolved issues and broken promises. 3750 is a good L3
switch in the Ethernet+IP arena, and just that.

On the other hand, ME6500 is a very good MPLS box. Besides doesn't
supporting VPLS (can be a member of an H-VPLS architeture, but doesn't
do VPLS) and limitations with EoMPLS requiring routerport instead of
switchport that can be designed around, it's simply a lot of routes,
labels, ACLs that can be handled with very little effort. Good
product, indeed.

They do not support LDP for label exchange, and from what I've been told by the PLM they never will.  12.2.40SE adds Multicast VRF (mVRF) lite support and SSM if you're interested.  This support was also added to the 3750ME.
