How to import translated addresses in OSPF domain

Our company has an OSPF domain between company's external router and ISP router.Our internal addresses are translated (NAT) on company's external router (the external interface).

The problem is that this translated addresses are not viewed by the OSPF domain. How can we configure the equipment in this case ?

Thanks in advance for your help

Re: How to import translated addresses in OSPF domain

You can 1) Add a static route to your external router for the translated address space, and redistribute that into OSPF, or 2) configure a loopback interface on your external router within the translated address space, and advertise that into OSPF. With option 2, you'll need to change the OSPF network-type on the loopback interface (say to point-to-point) to get round the loopback being advertised as a /32.
