Configuring Virtual Loopback and Null Interfaces
Step 4
end or commit
Example:
RP/0/RP0/CPU0:router(config-if)# end
or
RP/0/RP0/CPU0:router(config-if)# commit
Saves configuration changes.
• When you issue the end command, the system prompts you to commit changes:
Uncommitted changes found, commit them before exiting(yes/no/cancel)?
[cancel]:
• Entering yes saves configuration changes to the running configuration file, exits the configuration session, and
returns the router to EXEC mode.
• Entering no exits the configuration session and returns the router to EXEC mode without committing the configuration
changes.
• Entering cancel leaves the router in the current configuration session without exiting or committing the configuration
changes.
• Use the commit command to save the configuration changes to the running configuration file and remain within
the configuration session.
Step 5 show interfacestype instance
Example:
RP/0/RP0/CPU0:router# show interfaces Loopback0
(Optional) Displays the configuration of the loopback interface.
This example shows how to configure a loopback interface:
RP/0/RP0/CPU0:router# configure
RP/0/RP0/CPU0:router(config)# interface Loopback0
RP/0/RP0/CPU0:router(config-if)# ipv4 address 100.100.100.69 255.255.255.255
RP/0/RP0/CPU0:router(config-if)# ipv6 address 100::69/128
RP/0/RP0/CPU0:router(config-if)# end
Uncommitted changes found, commit them? [yes]: yes
RP/0/RP0/CPU0:router# show interfaces Loopback0
Loopback0 is up, line protocol is up
