Now, what if we want to make a change but we want to be sure we don’t lose

connection to the router? Well, we can do a commit confirm, this way if we

do lose connection our change will be rolled back!

RP/0/7/CPU0:R1#conf t

Sun Apr 1 22:23:01.154 UTC

RP/0/7/CPU0:R1(config)#int loop 666

RP/0/7/CPU0:R1(config-if)#ip add 6.6.6.6/32

Now, lets look at our commit confirmed options:

RP/0/7/CPU0:R1(config-if)#commit confirmed ?

<30-65535> Seconds until rollback unless there is a confirming commit

minutes Specify the rollback timer in the minutes

<cr> Commit the configuration changes to running

See, we can have a few seconds or a few minutes. Pretty cool!

RP/0/7/CPU0:R1(config-if)#commit confirmed 30

Sun Apr 1 22:23:19.344 UTC

Now, lets see if we have loop666:

RP/0/7/CPU0:R1(config-if)#do show int loop666

Sun Apr 1 22:23:34.353 UTC

Loopback666 is up, line protocol is up

Interface state transitions: 1

Hardware is Loopback interface(s)

Internet address is 6.6.6.6/32

MTU 1500 bytes, BW 0 Kbit

reliability Unknown, txload Unknown, rxload Unknown

Encapsulation Loopback, loopback not set,

Last input Unknown, output Unknown

Last clearing of "show interface" counters Unknown

RP/0/7/CPU0:R1(config-if)#

Yup, its there. Now we can wait a few seconds (30 or so) and do the show

interface command again.

RP/0/7/CPU0:R1(config-if)#do show int loop666

Sun Apr 1 22:25:09.361 UTC

Interface not found (Loopback666)

RP/0/7/CPU0:R1(config-if)#

All gone!
