For the fresh configuration of the router follow the below steps:

Sample procedure is as follows:

Router#config t

Router(config)#config-reg 0x2142

Router(config)#end

Router#show version (check the last line of the output)

Router#reload


When the router reloads, please type this command:


Router#write memory

Router#config t

Router(config)#config-reg 0x2102

Router(config)#end

Router#reload


At this moment, your router is at Factory default and ready to set any configuration.


Or another way is:


Router#write erase

or

Router#erase nvram:

On the 8xx, two more ways:


copy flash:c871-default-sdm.cfg startup-config

reload

(I made up the exact flash filename, do dir and you will see it)


or press the reset button just after turning on.
