Adding a loopback address to the FE of a Cisco 1721?

[whiteford]

Hi,

I was wondering how I can add a loopback address to the FE port of my Cisco 1721 router?

I am using the serial port, but not the FE for my lab and would like to bring this up.

Thanks

As far as I know it is:

#int loopback 0

#ip add x.x.x.x 255.255.255.255

Andy,

You just need to configure "no keepalive" under the interface.

int fa0

no keepalive

This will bring the interface is up/up state.

Would this work on a 2620 router as well?
