[c-nsp] shared experience if any

[R LAS]

We've experienced a lot of problems in the implementation of a c6880 VSS with IA modules, currentyl still not fixed.

Now Cisco is proposing to replace c6800 with c6500 and keep again the IA implementation.

I'm wondering about the difference in terms of hw/sw performaces (6800 against 6500), if the implementation is 
stable and if it's the right choice to point to a 6500 technology that is currently a bit old.

We're also thinking to move to Juniper....

Any advice/experience in appreciated.
