Re: EIGRP authentication using key chain with validity period

I think there was always open debate on this one. I personally do not
believe the proctors reload the racks as a matter of procedure. Not to say
it never happens either. The idea is to ensure your config sticks in case
something happens I think rather than due to proctors reloading the racks.

A proctor could tell you but probably would not. Anyone else would be
guessing at best.
