Configuring IP ADDRESS xxxxxxxxxxxxxxxxxxxxx

I'm copying the configuration from a router to another, but I found an IP that I can't copy to the new router.

There is Loopback interface created with the line: IP ADDRESS xxxxxxxxxxxxxxxx

How do I do to create this specification line in the new router? Because Cisco doesn't permit to create an IP Address with "xxxxxxxxxxx" .

Thanks for the help.

Re: Configuring IP ADDRESS xxxxxxxxxxxxxxxxxxxxx

I can't tell from your question if that is a valid ip address or not. You may want to delete the Loopback address on the new router.

config t

no nterface LoopbackX

and re-create it. He's some cisco documentation for you:

The following example enables loopback mode and assigns an IP network address and network mask to the interface. The loopback interface established here will always appear to be up:

interface loopback 0

ip address 131.108.1.1 255.255.255.0

Re: Configuring IP ADDRESS xxxxxxxxxxxxxxxxxxxxx

Actually the loopback interface declaration I have is exaclty this:

!

!

interface Loopback400

ip address xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

!

What I want, is to implement this declaration in the new router. The problem is to implement this ip address...

Do you know what is this sequency of xxxxxxxxxxxx ??
