Hello I have a remote router that will change its ip in a couple of
weeks, I would like to ad a second ip for this change. Can this be
done? thanks.

int x

ip address x.y.z.w 255.255.255.0 secondary


Note: The mask is just an example.

thanks I will try that

Do i have to add a second default gateway too? do i just repeat this
line with the new gateway
ip route 0.0.0.0 0.0.0.0 Mygatewayhere

what about the after the change can i just delete the primary ip?

thanks
