OSPF tab fields


Field Description
Enable
Enable or disable OSPF routing on the specified interface. The default is false.
HelloInterval
Length of time, in seconds, between hello packets. This value must be the same for all routers attached to a common network. The default is 10 seconds.
Note: When you change the Hello interval values, you must save the configuration file and reboot the switch for the values to be restored and checked for consistency.
RtrDeadInterval
Interval used by adjacent routers to determine if the router has been removed from the network. This interval must be identical on all routers on the subnet and a minimum of four times the Hello Interval. To avoid inter operability issues, the RtrDeadInterval value for the OSPF interface needs to match with the RtrDeadInterval value for the OSPF virtual interface.The default is 40 seconds.
DesigRtrPriority
The priority of this interface. Used in multiaccess networks. This field is used in the designated router election algorithm. The value 0 indicates the router is not eligible to become the designated router on this particular network. In the event of a tie in this value, routers will use their router id as a tie breaker. The default is 1.
Metric
The metric for this type of service (TOS) on this interface. The value of the TOS metric is (10^9 / interface speed). The default is 1.
FFFF= There is no route for this TOS.
POS/IPCP links = defaults to 0.
0 = The interface speed is used as the metric value when the state of the interface is up.
AuthType
Type of authentication required for the interface.
  • none = No authentication required.
  • simple password = All OSPF updates received by the interface must contain the authentication key specified in the interface AuthKey field.
  • MD5 authentication = All OSPF updates received by the interface must contain the md5 key.
AuthKey
Key (up to 8 characters) required when simple password authentication is specified in the interface AuthType field.
AreaId
Dotted decimal value to designate the OSPF area name.
Note: The area name is not related to an IP address. You can use any value for the OSPF area name (for example, 1.1.1.1 or 200.200.200.200).
AdvertiseWhenDown
If true, the network on this interface will be advertised
as up, even if the port is down. The default is false.

Note: When you configure a port without any link and enable AdvertiseWhenDown, it will not advertise the route until the port is active. Then the route will be advertised even when the link is down. To disable advertising based on link states, disable AdvertiseWhenDown.
IfType
Type of OSPF interface (broadcast, NBMA, or passive).
Note: Before changing an OSPF interface type, you must first disable the interface. If it is an NBMA interface, you must also delete all configured neighbors.
PollInterval
Length of time, in seconds, between hello packets sent to an inactive OSPF router. Neighbors must have the same PollInterval value.
