Its returning an error for a reason. You cannot do this! Each
interface to the IP stack has to have a different IP address. Maybe
what you want is that the node acts as an ethernet bridge with two
ethernet ports? You then have one interface to the IP stack and so can
have one IP address. Just be careful of loops.
