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.

• Point-to-multipoint. An interface to a point-to-multipoint network that

supports multiple routers in a partial mesh configuration. Bay Networks

supports the standard OSPF point-to-multipoint interface and also provides a

proprietary point-to-multipoint solution for routers running OSPF in star

frame relay topologies. For more information about the Bay Networks

proprietary point-to-multipoint solution, see “

Using Point-to-Multipoint

Interfaces in a Star Topology” on page 6-23.

• 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.

window.

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 6-37.
