About the only way I can think of is to use CRB or IRB

You cannot use unnumbered,

Rack1R5(config-if)#ip unnumbered ethernet 0/1
Point-to-point (non-multi-access) interfaces only

Hello,

Multilink will not work... you need to "unnumber" one of the interfaces to
the other interface as follows:

Ethernet 0/0
ip address 66.106.47.230 255.255.255.252

Ethernet 0/1
Ip unnumbered Ethernet0/0

This is usually not a good way to do this though. What is it exactly you
are trying to accomplish, as there may be a better method.

I need help like right now - BIG Thanks to everyone that responds.

I am trying to put the exact same IP Address on 2 different ethernet
interfaces. The only thing that I could think of is - interface multilink
1, but it is not working, here is my config:

interface Multilink1
 ip address 66.106.47.230 255.255.255.252
 ppp multilink
 multilink-group 1

Ethernet 0/0

no ip address
 ip load-sharing per-packet
 no ip mroute-cache
 ppp multilink
 multilink-group 1

Ethernet 0/1

no ip address
 ip load-sharing per-packet
 no ip mroute-cache
 ppp multilink
 multilink-group 1
