Command

Copy Startup-config Running-config

Use

This command lets you merge your saved config with the running configuration. The command overwrites conflicting infomation such as interface IP addresses but keeps new information in the config.

Syntax

R1#copy startup-config running-config

Example

In the below example R1's saved configuration is merged with its running configuration.

First lets change a few things.

Current interface summary Interface IP-Address OK? Method Status Protocol FastEthernet0/0 10.1.1.1 YES NVRAM up up Loopback0 1.1.1.1 YES NVRAM up up R1(config)#int lo0 R1(config-if)#ip add 5.5.5.5 255.255.255.255 R1(config-if)#int lo1 R1(config-if)#ip add *Mar 1 03:06:08.175: %LINEPROTO-5-UPDOWN: Line protocol on Interface Loopback1, changed state to up R1(config-if)#ip add 11.11.11.11 255.255.255.255

Now lets merge the configuration, notice that R1's loopback reverted back to 1.1.1.1 while it kept the new loopback1 interface.
