How to configure multiple loopback interfaces (lo0, lo1, lo2...)
 

I repeat the question:

How can I configure multiple loopback interfaces (lo0, lo1, lo2...)??

Thanks

Arkin

And you would want to do this why?

I need it to do some works. Please Nobody knows how can be replicated de loopback interfaces (lo0,lo1,lo2........)??????????

Arkin

I don't believe that it can be done.

You might be able to find a way to multicast it (i.e. lo:0, lo:1). I have no idea though, I've never used multicasting really. I'm just hopefully giving you a direction to look :)

I found webs that say that is posible to replicate loopback interfaces, but they don't say how. Thanks itsme86 for the answer.

I was looking for this as well. Figured it out, so I thought I'd post the answer.

This is how it is done with Fedora:

1) Copy the existing loopback interface:

cd /etc/sysconfig/network-scripts
cp ifcfg-lo ifcfg-lo:1

2) Edit the interface ifcfg-lo:1
DEVICE=lo
IPADDR=127.0.0.1
NETMASK=255.0.0.0
NETWORK=127.0.0.0
ONBOOT=yes
NAME=loopback

3) Change the DEVICE= to the alias # (lo:1)

4) Change the IPADDR,NETMASK,NETWORK

3) If you need more loopback interfaces, just copy again and add alias # (lo:2,lo:3,etc)

Hope this helps others.

Hello

what to do if I have now to remove lo:1 ?
I removed file ifcfg-lo:1 but it was not enough .
