[c-nsp] Minimum hardware for IOS XR?

[Marc Binderberger]

Hello,

plus a few more conditions: from 3.8 onwards your engine3 needs 1GB
memory, otherwise it won't boot anymore. And the RP may run short of
memory with less than 2 GB. And the flashdisk should be 1GB (maybe you
get away with 512M ...).


Regards, Marc
