default value, use the no form of this command.
Command Syntax
ip ospf network {broadcast | non-broadcast | point-to-multipoint [non-broadcast] |
point-to-point}
no ip ospf network
broadcast Sets the network type to broadcast.
non-broadcast Sets the network type to nonbroadcast multiaccess (NBMA).
point-to-multipoint [non-broadcast] Sets the network type to point-to-multipoint. The
optional non-broadcast keyword sets the
point-to-multipoint network to be nonbroadcast. If you
use the non-broadcast keyword, the neighbor
command is required.
point-to-point Sets the network type to point-to-point.
Default
Depends on the network type.

Interface configuration
Usage
Using this feature, you can configure broadcast networks as NBMA networks when, for example,
routers in your network do not support multicast addressing. You can also configure nonbroadcast
multi-access networks as broadcast networks. This feature saves you from needing to configure
neighbors.
Configuring NBMA networks as either broadcast or nonbroadcast assumes that there are virtual
circuits from every router to every router or fully meshed networks. However, there are other
configurations where this assumption is not true. For example, a partially meshed network. In these
cases, you can configure the OSPF network type as a point-to-multipoint network. Routing between
two routers that are not directly connected will go through the router that has virtual circuits to both
routers. You need not configure neighbors when using this feature.
If this command is issued on an interface that does not allow it, this command will be ignored.
OSPF has two features related to point-to-multipoint networks. One feature applies to broadcast
networks; the other feature applies to nonbroadcast networks:
„
On point-to-multipoint, broadcast networks, you can use the neighbor command, and you must
specify a cost to that neighbor.
„ On point-to-multipoint, nonbroadcast networks, you must use the neighbor command to identify
neighbors. Assigning a cost to a neighbor is optional.
Examples
The following example sets your OSPF network as a non-broadcast network:
interface eth-0-1
no switchport
