router ospf
process-id
Configure an OSPF router process and enter
into router configuration mode.
neighbor
ip-address cost number
Designate a neighbor and allocate a metric for
it
For each neighbor wishing to designate its metric, repeat step 4. Otherwise use the value designated by
command “ip ospf cost”.
60.3.5 Configuring Non-Broadcasting Network
Because there are many routers in the OSPF network, so there must be one DR elected for the network. If the
broadcasting ability is not configured, it is requested to perform parameter configuration for the selection
process.
These parameters only carry out configuration on the routers that are eligible to become DR or BDR.
Under router configuration mode, use the following command to configure routers of non-broadcasting network
which are mutually related:
Command Purpose
neighbor
ip-address [
priority
number]
[
poll-interval
seconds]
Configure the router connected to the non-broadcasting
network
You can designate the following parameters for a neighbor router:
 The precedence of neighbor router.
 Non-broadcasting poll interval.
 Interface accessible to the neighbor
In point to multiple point, non-broadcasting network, you can use command “neighbor” to designate neighbor
relation. Allocate an optional priority.
In the previous software versions, some users configure point to multipoint connections on non-broadcasting
media (IP over ATM), so the router cannot dynamically discover its neighbor router. This feature permits the
usage of command “neighbor” on point to multipoint interface.
In a point to multipoint network, the router supposes all neighbors have the same metric. This value can be
configured through the command “ip ospf cost”. In fact, as the bandwidth of each neighbor is different, the
value should also be different. This feature only applies to point to multiple point interfaces.
Under interface configuration mode, use the following command to configure point to multiple point interfaces
on media that do not support broadcasting.
Command Purpose
ip ospf network point-to-multipoint
non-broadcast
Configure point to multiple point interface on non-
broadcasting media
