Hi I am new to routers, I am playing around with a cisco 2600 and was wondering dow to delete a seconary IP address from interface fastethernet0/0.1 ? I know how to change it but i want to get rid of the secondary ip address altogether.

Thanks!
 
No ip address xxx.xxx.xxx.xxx 255.xxx.xxx.xxx
You have to use the whole address so you don't delete both ips addresses.

Tip Most lines of config can be removed by using the "no" form of the command.

For example: these config lines
interface fastethernet0/0.1
ip address 172.1.100.3 255.255.255.0


can be changed by the following

router (configif)# no ip address
 
Does putting no before the command work when removing telnet access?
