[c-nsp] 6500-MSFC2(c6sup22) - MPLS

[David Freedman]

Oh, and despite fixing the LDP problems, you will still need the OSM for 
SupII in order to do the actual tag-switching :)

Last router signals label 3 (implicit null) that is instructing neighbor to remove transit label and send only "VPN" label on that link. Add on another MPLS box (P router( in between and you will get transport/tunnels labels.

I have no need for any OSM stuff. Do I need the 720 Sup?  Or do I need to run the big c6sup222 12.2 images opposed to the
