Not at all the same... With JunOS, I can have the changes I made running =
for days, but, when some problem is later discovered I can still =
rollback to the previous (or several revisions back). I can easily =
compare the current config to several previous revisions, etc.
Additionally, with JunOS I can make all my changes, verify them =
syntactically, compare the changes made to the previous configuration =
all without having the changes take effect during the process. Then, =
when I'm satisfied I have it right, I commit the configuration. If =
you've ever had to play the IOS ACL rotation game, you know how =
wonderful this feature is.
Cisco's half-hearted attempt to play catch-up here is woefully =
inadequate.
