Attribute Attribute Description
OSPF Parameters on Network Interface
Metric <1-32767> Assign the link cost for this interface that advertised in the
router’s link state advertisement for this interface.
The Metric is an indication of the cost of the route. If multiple
routes exist on a network ID, the Metric is used to decide which
route is taken. The route with the lowest Metric is the preferred
route. If you enter a high number for the Metric, this interface will
not be used as much as an interface with a lower Metric.
Default:1.
Transit delay (s) <1-3600 > Set the estimated round-trip transit delay in the network
connected to the interface.
Default: 1.
Dead Interval <1-32767> Set the maximum number of seconds the router waits to receive
the next hello before considering the adjacent router as non
operational.
Default: 40.
Link type Broadcast
Point -To-Point
NBMA
Select the type of interface that describes your network
configuration. The possible values are:
Broadcast: A broadcast network supports multiple routers and
can send a broadcast/multicast message to all routers.
Point-To-Point: A point-to-point network joins a single pair of
OSPF routers.
NBMA: A Non-Broadcast-Multi-Access (NBMA) network
supports multiple routers and cannot broadcast/multicast to all
routers.
Default: Broadcast.
Retransmit
interval (s)
<1-3600> Set the number of seconds the router waits before retransmitting
after a time-out occurs.
Default: 5.
Poll interval <1-32767> Define the period of time the router must keep sending hello
packets to an adjacent router that is considered non operational.
Default:120.
Router priority <0-255> Assign a priority to the BCM router. A value of 0 indicates that
the BCM system cannot become the designated router.
Default: 1.
Hello interval (s) <1-32767> Define how frequently the router must send “hello packets” on an
interface.
Default:10.
Password <alphanumeric> Define an authentication password, if you selected Password as
the authentication type in the Authentication Type box on the
OSPF Global Parameters window.
There is no default value provided because the Authentication
Type is set to None by default.
Note: The password you choose must conform to the password
policy used for your BCM system.
