[c-nsp] Sup720-3A: anyone with 'mls mpls enable' experience?

[Pete Templin]

I'm working a school project with a truckload of original Sup720s in 
6500s.  Given the funding arrangements, replacing these units is, shall 
we say, unlikely.  Should we find issues where MPLS would be beneficial, 
does anyone have experience with the global command 'mls mpls enable'? 
If so, could you please share your experiences?

Thanks,

Pete
