10.2.4.8OSPF Network Type

There are 4 types of OSPF network. Broadcast network, NBMA (Non-broadcast-multiple- access) network, Point-to-multipoint network and Point-to-point network.

User can configure OSPF network as a Broadcast network or Non-broadcast network type. For example, if the network does not support multicasing it can be configured Non- broadcast type from Broadcast type, and NBMA network as a Frame relay can be broad- cast network type.

NBMA type network need virtual circuit to connect routers. But Point-to-multipoint type uses virtual circuit on part of network to save the management expenses. It does not to need to configure Neighbor router to connect routers which are not directly connected. It also saves IP resources and no need to configure the process for destination router. It supports those benefits for stable network services.

Generally, the routers and Layer 3 switches are using Broadcast type network. To select an OSPF network type, use the following command.

Command	Mode	Description
ip ospf network {broadcast
non-broadcast point-to-multi-	Interface	Selects an OSPF network type.
point point-to-point}

10.2.5Non-Broadcast Network

To operate NBMA type network, neighbor router configuration is needed. And IP address, Priority, Poll-interval configuration as well. Priority is information for designate router se- lection and it configured [0] as a default. Poll-interval is the waiting time to re-get the hello packet from dead Neighbor router. It configured 120 seconds as a default.

To configure a router communicated by non-broadcast type, use the following command.

Command	Mode	Description
neighbor A.B.C.D cost <1-65535>
neighbor A.B.C.D priority <0-255>
neighbor A.B.C.D priority <0-255>poll-interval		Configures a neighbor router of NBMA
<1-65535>	Router
		type.
neighbor A.B.C.D poll-interval <1-65535>
neighbor A.B.C.D poll-interval <1-65535>prior-
ity <0-255>
