DES-7200 Configuration Guide Chapter 4 OSPF
Configuration
4-9
To configure the point-to-multipoint network type, execute the following
commands in the interface configuration mode:
Command Function
DES-7200(config-if)# ip ospf network
point-to-multipoint
Configure the point-to-multipoint network
type for an interface.
DES-7200(config-if)# exit
Exit to the global configuration mode.
DES-7200(config)# router ospf 1
Enter the routing process configuration
mode.
DES-7200(config-router)#
neighbor ip-address cost cost
Specify the cost of the neighbor (optional).
Note
Although the OSPF point-to-point network is a non-broadcast network, it can
allow non-broadcast networks to have broadcast capability by using the frame
relay, X.25 mapping manual configuration or self-learning. Therefore, you do
not need to specify neighbors when you configure the point-to-multipoint
network type.
4.2.3.2 Configuring Non-broadcast Network
When the OSPF interface works in the non-broadcast network, you can configure
it to the NBMA or the point-to-multipoint non-broadcast type. Since it cannot
dynamically discover neighbors without the broadcast capability, you must
manually configure neighbors for the OSPF interface working in the
non-broadcast network.
You can configure the NBMA network type in the following conditions:
When a non-broadcast network has the fully meshed topology;
You can set a broadcast network as the NBMA network type to reduce the
generation of the broadcast packets and save the network bandwidth, and
also avoid arbitrary reception and transmission of routers by some degree.
The configuration of the NBMA network should specify the neighbor. For
there is the choice to specify the routers, you should determine which router
is the designated router. For this reason, it is necessary for you to prioritize
rotuers. The higher the router’s pirority is, the higher possibility of being the
designated router is.
To configure the NBMA network type, execute the following commands in the
interface configuration mode:
