ip ospf network

Configures the network type for the interface. Point-to-point can support unnumbered links, which requires less processing by OSPF.

ip ospf network { broadcast | non-broadcast | point-to-point }
no ip ospf network

Network type is broadcast.

broadcast
Network type is broadcast.
non-broadcast
Network type is non-broadcast. An interface can be configured to send OSPF traffic to its neighbor as unicast packets rather than multicast packets.
point-to-point
Network type is point-to-point.

Interface subtype configuration mode

On a non-broadcast interface, the devices at either end of the interface must configure non-broadcast interface type and the neighbor IP address. There is no restriction on the number of devices sharing a non-broadcast interface.

To configure an OSPF interface as a non-broadcast interface, the feature must be enabled on a physical interface or a VE, following the ip ospf area statement, and then specify the IP address of the neighbor in the OSPF configuration. The non-broadcast interface configuration must be done on the OSPF devices at either end of the link.

The no form of the command removes the network-type configuration.

The following example configures an OSPFv2 point-to-point link on a specific OSPFv2 Virtual Ethernet (VE) interface. 


device# configure terminal
device(config)# interface interface ve 1
device(config-vif-1)# ip ospf network point-to-point

The following example configures an OSPFv2 broadcast link on a specific OSPFv2 Virtual Ethernet (VE) interface. 


device# configure terminal
device(config)# interface interface ve 1
device(config-vif-1)# ip ospf network broadcast
