OSPF 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-
point
|
point-to-point
}
Interface
Selects an OSPF network type.
10.2.5 Non-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.
