Customizing OSPF Services

Specifying the Interface Type
OSPF supports the following types of interfaces:
Broadcast. An interface connected to a broadcast network that supports
multiple routers. OSPF can address a single physical message to all attached
routers. Examples of such a network are Ethernet, FDDI, and token ring.
Nonbroadcast multi-access (NBMA). An interface to an NBMA network that
supports multiple routers. However, OSPF cannot address a single physical
message to all routers. Examples of such a network are frame relay and X.25.
Point-to-point. An interface to a point-to-point network that joins a single pair
of OSPF routers. An example of such a network is a network of synchronous
lines or a direct mode frame relay environment.
Point-to-multipoint. An interface to a point-to-multipoint network that
supports multiple routers in a partial mesh configuration. An example of such
a network is a group mode frame relay environment. Nortel Networks
supports the standard OSPF point-to-multipoint interface and also provides a
proprietary point-to-multipoint solution.
Passive. A passive interface only receives advertisements. OSPF cannot use it
to form neighbor relationships, accept Hello messages, or send
advertisements. On other interfaces, OSPF advertises the network attached to
a passive interface as a stub network.

Note:
If the interface is connected to an NBMA network, you need to
configure neighbors manually. For instructions on manually configuring
neighbors, see
Configuring a Neighbor on an NBMA Interface” on page 6-36.
