It seems like Cisco is following Juniper's foot print. Recently I had some
times to get familiar with JUNOS and some of Juniper routers. With JUNOS,
all you have to do is just type "rollback 1" and you are back using your
older config. With JUNOS 6.1, 6.2 and now that 6.3 is out, you can go back
up to 49 previous configs and if you ever want to go back to any of these
configs just use the command rollback and the number. you have to commit
your changes after each rollback.

Subject: config replace
While testing some new hardware I stumbled across a new command I
think can be quite useful. It is "config replace". What it does is
aloows you to load another config onto flash and "replace" the existing
config with a new config in a nice quick clean fashion. With the
optional "list" command the IOS will list all of the changes.
USBtest#conf replace usbflash0:running-config list
This will apply all necessary additions and deletions
to replace the current running configuration with the
contents of the specified configuration file, which is
assumed to be a complete configuration, not a partial
configuration. Enter Y if you are sure you want to proceed. ? [no]: y
!Pass 1
!List of Commands:
no hostname Replacetest
no interface Loopback0
interface FastEthernet0/0
no ip address 172.28.64.229 255.255.255.0
no router rip
hostname MAYDAY
interface FastEthernet0/0
ip address 172.28.64.222 255.255.255.0
end
My new config I replaced the old one with had no loopback interface
or router rip and had a new hostname. With replace the extraneous
commands are deleted automatically, no need to "no" them out in a
config file and no reloads!
Looks like it is available in 12.3, not sure exactly when it first
came out.
