Configuring OSPF
Modifying Interface Parameters
There are several interface parameters that can be modified on a specified interface. Most of these deal
with timer settings.
The cost parameter and the priority parameter help to determine the cost of the route using this interface,
and the chance that this interface's router will become the designated router, respectively.
The following table shows the various interface parameters that can be set:
ip ospf interface dead-interval
ip ospf interface hello-interval
ip ospf interface cost
ip ospf interface poll-interval
ip ospf interface priority
ip ospf interface retrans-interval
ip ospf interface transit-delay
These parameters can be added any time. (See
mation.) For example, to set an the dead interval to 50 and the cost to 100 on interface vlan-213, enter the
following:
-> ip ospf interface vlan-213 dead-interval 50
-> ip ospf interface vlan-213 cost 100
To set an the poll interval to 25, the priority to 100, and the retransmit interval to 10 on interface vlan-213,
enter the following:
-> ip ospf interface vlan-213 poll-interval 25 priority 100 retrans-interval 10
To set the hello interval to 5000 on interface vlan-213, enter the following:
-> ip ospf interface vlan-213 hello-interval 5000
To reset any parameter to its default value, enter the keyword with no parameter value, as shown:
-> ip ospf interface vlan-213 dead-interval
Note. Although you can configure several parameters at once, you can only reset them to the default one
at a time.
OmniSwitch AOS Release 7 Advanced Routing Configuration Guide
Configures OSPF interface dead interval. If no hello packets are
received in this interval from a neighboring router the neighbor is con-
sidered dead.
Configures the OSPF interface interval for NBMA segments.
Configures the OSPF interface cost. A cost metric refers to the net-
work path preference assigned to certain types of traffic.
Configures the OSPF poll interval.
Configures the OSPF interface priority. The priority number helps
determine if this router will become the designated router.
Configures OSPF interface retransmit interval. The number of sec-
onds between link state advertisement retransmissions for adjacencies
belonging to this interface.
Configures the OSPF interface transit delay. The estimated number of
seconds required to transmit a link state update over this interface.
