[c-nsp] Downsides of combining P and PE functions into a single box

[Herro91]

Hi Group,

I'd like to get some feedback from the list as to potential downsides of
combining P and PE functionality into a single router. Besides the obvious
configuration concerns - i.e. changes being made on an edge box that is also
a core, as well as additional heavy lifting for a P router - are there other
items to be concerned about?

This would be on high end distributed forwarding hardware (not the little
stuff). TE is definitely a possibility in addition to L2/L3VPNs/VPLS.

Please let me know if you need additional info to make the right
conclusions.


Thanks in advance!
