Try doing 'ip ospf network point-to-point' on the loopback interface.

        hi, everyone
        when impletminting the NAT, "Practical study" said i could creat a loopback
        interface as anchor to make sure the outside local address reachable.
        my config is as follow:
        inter loopback 1
         ip addr 10.1.1.1 255.255.255.0
        router ospf 1
         net 10.0.0.0 0.0.0.255 area 0
        i try to use loopback interface to represent the address range between
        10.1.1.2 through 10.1.1.254.
        but when i issue " show ip route", only 10.1.1.1/32 appeared, so that mean
        10.1.1.x is still unreachalbe.
        so could i generate a route about loopback interface with /24 mask if that
        router is not a ABR and ASBR (no static route is allowed)
        thanks
        james
