3. Basic Configuration Options

Ok, we have seen the basic COMMIT option – but what other options do we have

for configuration mode? Well, we have a few to choose from.

First, what if I am making changes and decide I don’t want them? You have a

few options. First you could just exit all the way out.

RP/0/7/CPU0:R1(config)#exit

Uncommitted changes found, commit them before exiting(yes/no/cancel)?

[cancel]: no

And once you exit out, all your changes are lost.

Ok, that is one option. Another is clear. To demonstrate we will create

loopback 666:

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

Sun Apr 1 22:18:52.956 UTC

RP/0/7/CPU0:R1(config)#int loop666

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

Ok, let’s check the candidate configuration:

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

Sun Apr 1 22:19:03.438 UTC

Building configuration...

!! IOS XR Configuration 4.1.1

interface Loopback666

ipv4 address 6.6.6.6 255.255.255.255

end

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

OK, we have it in the candidate configuration now. We changed our mind about

that – so lets clear it.

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

Now check the candidate configuration again.

RP/0/7/CPU0:R1(config)#show config

Sun Apr 1 22:19:34.733 UTC

Building configuration...

!! IOS XR Configuration 4.1.1

end

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

There, all gone!
