Enter the area ID in the field, using IP address format in dotted decimal notation (e.g.,
10.10.0.0
). The
default entry is
0.0.0.0
, the backbone. Your entry also appears in the
OSPF Area
list on the
Configuration
| System | IP Routing | OSPF Areas
screen.
OSPF Priority
This entry assigns a priority to the OSPF router on this interface. OSPF routers on a network elect one
to be the Designated Router, which has the master routing database and performs other administrative
functions. In case of a tie, the router with the highest priority number wins. A
0
entry means this router
is ineligible to become the Designated Router.
Enter the priority as a number from
0
to
255
. The default is
1
.
OSPF Metric
This entry is the metric, or cost, of the OSPF router on this interface. The cost determines preferred
routing through the network, with the lowest cost being the most desirable.
Enter the metric as a number from
1
to
65535
. The default is
1
.
OSPF Retransmit Interval
This entry is the number of seconds between OSPF Link State Advertisements (LSAs) from this
interface, which are messages that the router sends to describe its current state.
Enter the interval as a number from
0
to
3600
seconds. The default is
5
seconds, which is a typical value.
OSPF Hello Interval
This entry is the number of seconds between Hello packets that the router sends to announce its presence,
join the OSPF routing area, and maintain neighbor relationships. This interval must be the same for all
routers on a common network.
Enter the interval as a number from
1
to
65535
seconds. The default is
10
seconds, which is a typical
value.
OSPF Dead Interval
This entry is the number of seconds for the OSPF router to wait before it declares that a neighboring
router is out of service, after the router no longer sees the neighbor’s Hello packets. This interval should
be some multiple of the Hello Interval, and it must be the same for all routers on a common network.
Enter the interval as a number from
0
to
65535
seconds. The default is
40
seconds, which is a typical
value.
OSPF Transit Delay
This entry is the estimated number of seconds it takes to transmit a link state update packet over this
interface, and it should include both the transmission and propagation delays of the interface. This delay
must be the same for all routers on a common network.
Enter the delay as a number from
0
to
3600
seconds. The default is
1
second, which is a typical value.
