G'Day Group,

                  I cannot remember this right now so I'm calling out for
assistance with this, There are 4 ways to advertise a loopback interface into
ospf and maintain its original subnet (eg./24) rather then a /32.

a. Use ip ospf point-to-point on the loopback interface and advertise the
interface
b. route-map matching the loopback interface and then redistribute connected
subnets route-map
c. area x range 'address' 'subnet' under the ospf process
d. ?

I cannot remember what the 4th is ? Any ideas ?

Thanks

John
