'The OSPF interface type. By way of a default, this field may be intuited from the corresponding value of ifType. Broadcast LANs, such as Ethernet and IEEE 802.5, take the value 'broadcast'. Medias which allow multiple devices to be connected but don't support a broadcast mechanism, such as X.25, take the value 'nbma'. Point to Point protocols take the value of 'pointtopoint'. Non-fully meshed technologies would take the value of either 'ietf' or 'pmp'. Passive interface take the value of 'passive'. An example topology is a Frame Relay cloud that does not have a PVC between every device on the cloud. broadcast (1), nbma (2), pointToPoint (3) point to multipoint - proprietary (4) point to multipoint - standard (5) passive (6)
