4.4 OSPF Over Non-Broadcast Networks
4.4.6 Broadcast interfaces
This approach is a workaround for using the "neighbor" command which statically lists all existing neighbors. The interface will be logically set to broadcast and will behave as if the router were connected to a LAN. DR and BDR election will still be performed, so special care should be taken to assure either a full mesh topology or a static selection of the DR based on the interface priority. The command that sets the interface to broadcast is:

ip ospf network broadcast

The Multipoint configuration with broadcast network is shown in the figures to the left. (see Router Tokyo and Router Melbourne command outputs).
