You have to pick a number. The number we picked seems reasonable to
us. Most people seem to agree since they seldom change it.

Regardless of which Hold time default, juniper's or cisco's choice, if
you have a hold timer expire you have a problem. I believe you want to
diagnose why you lost connectivity for so long rather than
concentrating on what the hold timer value should be.
