[c-nsp] Sup 720 dual engine configurations

[George Antoniou]

Hi,

We're contemplating installing 2 sup720 engine per chassis -- does it
make sense to have that type of redundancy / spare?  Are there tech
notes on ensuring that the config is done correctly (dependency
analysis) -- i.e. no impact to bgp, igrp, etc when the primary engine
fails?

Any links, thoughts, experience-shared would be greatly appreciated.

Thanks,
 
George
