cost number

(Optional) Assigns a cost to the neighbor, in the form of an
integer from 1 to 65535. Neighbors with no specific cost
configured will assume the cost of the interface, based on the ip
ospf cost command. For point-to-multipoint interfaces, the cost
keyword and the number argument are the only options that are
applicable. This keyword does not apply to nonbroadcast
multiaccess (NBMA) networks.


Default

No configuration is specified.


Command Mode

Router configuration


Usage

One neighbor entry must be included in the switch configuration for each known nonbroadcast network
neighbor. The neighbor address must be on the primary address of the interface.
If a neighboring router has become inactive (hello packets have not been received for the Router Dead
Interval period), it may still be necessary to send hello packets to the dead neighbor. These hello
packets will be sent at a reduced rate called Poll Interval.
When the router first starts up, it sends only hello packets to those routers with nonzero priority, that is,
routers that are eligible to become designated routers (DRs) and backup designated routers (BDRs).
After the DR and BDR are selected, DR and BDR will then start sending hello packets to all neighbors
in order to form adjacencies.


Examples

The following example declares a router at address 192.168.3.4 on a nonbroadcast network, with a
priority of 1 and a poll interval of 180 seconds:
router ospf
neighbor 192.168.3.4 priority 1 poll-interval 180

15.29 network area (OSPF)

To define the interfaces on which Open Shortest Path First (OSPF) runs and to define the area ID for
those interfaces, use the network area command in router configuration mode. To disable OSPF
routing for interfaces defined with the address wildcard-mask pair, use the no form of this command.


Command Syntax

network {ip-address wildcard-mask | ip-address/prefix-length} area area-id
