ROUTER(config-if)#ip ospf net ?
  broadcast Specify OSPF broadcast multi-access network
  non-broadcast Specify OSPF NBMA network
  point-to-multipoint Specify OSPF point-to-multipoint network
  point-to-point Specify OSPF point-to-point network

ROUTER(config-if)#ip ospf net

Try ip ospf network point-to-point

Depends on IOS version though, this is 12.0.7(T)

Subject: loop back interfaces and ospf

Hi all,

does anyone know how to get OSPF to advertise a loopback as a subnet vs a
host route?

If I have Router 1 with a loop back interface, ip address 172.16.220.1, and
that loopback is in area 0.
Router 2, also in area 0, has a host route in it's ip routing tables vs. a
subnet route for 172.16.220.0

Here's the setup

172.16.220.1
loopback 0 --------R1 --------------Serial ---------R2
                    172.16.1.0
on router 1 and router 2:

router ospf 1
network 172.16.0.0 0.0.255.255 area 0

I thought about using area 0 range 172.16.220.0 255.255.255.0
but it did not make a difference.

Thanks,

Julie Ann
