Table 205 IP OSPF Parameters
Attribute Description
Metric This field allows you to 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.
The possible values are 1 to 32767 .
The default value is 1 .
Interface Type Allows you to select the type of interface that describes your network configuration. The possible
values are:
Broadcast : A broadcast network supports multiple routers and addresses a single physical
message to all routers.
P2P : 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
address a single physical message to all routers.
The default value is Broadcast .
Router Priority Allows you to assign a priority to the Business Communications Manager router. The possible
values are
0 to 255 . A value of 0 indicates that the Business Communications Manager system
cannot become the designated router.
The default value is
1 .
Transit Delay Allows you to set (in seconds) the estimated round-trip transit delay in the network connected to
the interface. The values are
1 to 3600 seconds.
The default value is 1 .
Retransmit
Interval Allows you to set the number of seconds the router waits before retransmitting after a time-out
occurs. The values are
1 to 3600 seconds.
The default value is 1 .
Hello Interval Allows you to define how frequently the router must send “hello packets” on an interface. The
values are
1 to 32767 seconds.
The default value is 10 .
Dead Interval Allows you to set the maximum number of seconds the router waits to receive the next hello
before considering the adjacent router as non operational. The values are
1 to 32767 seconds.
The default value is 40 .
Poll Interval Allows you to define the period of time the router must keep sending hello packets to an adjacent
router that is considered non operational. The values are
1 to 32767 seconds.
The default value is 120 .
MTU Allows you to specify the Maximum Transmission Unit for this interface. The values are 1 to
10000 .
The default value is 1500 .
Password Allows you to 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 Business
Communications Manager system. For more information about the password policy, refer to
“Setting password policy” on page 134 .
