Parameters Examples Error messages |
The Add OSPF Interface (ADDOSPFIFC) command defines an OSPF interface that the OMPROUTED server will add into the OSPF routing protocol implementation and set the different parameters needed for each interface.
With this command both IPv4 and IPv6 OSPF Interfaces can be configured.

| Top |
Specifies the internet address of a configured logical interface in the system. The interface identifier can be an IPv4 or IPv6 address.
The interface identifier can also be an alias name of an logical interface.
| Top |
Specifies the profile created for point-to-point connection to a host at the remote end. This profile will be used later when the point-to-point link is being active.
| Top |
Specifies the OSPF area to which this interface attaches. You can specify the backbone area (internet address 0.0.0.0) or any area previously defined by running the Add OSPF Area (ADDOSPFARA) command.
| Top |
Specifies the frequency of retransmitting link-state update packets, link-state request packets, and database description packets.
Note: If this parameter is set too low, needless retransmissions will occur that could affect performance and interfere with neighbor adjacency establishment. It should be set to a higher value for a slower machine.
| Top |
Specifies the estimated number of seconds that it takes to transmit link-state information over the interface.
| Top |
Specifies the value for a broadcast and non-broadcast multi-access networks in order to elect a designated router. The router with the highest priority value will be elected.
| Top |
Specifies the number of seconds between OSPF hello packets to be sent out on this interface. This value must be the same for all routers attached to a common network.
| Top |
Specifies the length of time that the database exchange process cannot exceed. If the interval elapses, the procedure will be restarted. This value must be larger than the interval for hello.
| Top |
Specifies the length of time after not having received OSPF hello packets that an OSPF neighbor is declared to be down.
| Top |
Specifies the cost of sending a data packet on the interface, expressed in the link state metric. This is advertised as the link cost for this interface in the router-LSA. The cost of an interface must be greater than zero.
| Top |
Specifies whether this interface is designated as primary or backup by OSPF. When there is more than one local interface defined on the same IPv4 subnet, IPv6 subnet, or link, OSPF sends all routing traffic on the designated primary interface.
| Top |
Specifies, for Point-to-Point links, if this interfaces can have a connection to a network/subnet or host. This parameter only applies to IPv4.
| Top |
Specifies the security schema used on the network where this interface is attached. If this parameter is not specified the security schema will be taken from the area's security schema. This parameter is ignored for OSPF IPv6 interfaces.
| Top |
Specifies the combination of parameters needed for cryptographic authentication.
Element 1: Authentication key identifier
Element 2: Authentication key
For *NONE authentication type, this parameter element is not required and is ignored if specified.
For authentication type *PASSWORD, this parameter element must specify a password for OSPF routers that are attached to this subnet. Valid values are any character string up to 8 characters in length coded within single quotation marks, or any hexadecimal string up to 8 bytes (16 hexadecimal characters) long beginning with X followed by the hexadecimal value enclosed in single quotation marks.
For authentication type *MD5, this parameter must specify the 16-byte MD5 authentication key for OSPF routers attached to this subnet. The standard method is with a 16-byte hexadecimal string beginning with X followed by the hexadecimal value enclosed in single quotation marks.
| Top |
Specifies whether link state advertisements (LSAs) are periodically refreshed or not over this interface.
Only LSAs with real changes will be advertised. This parameter is ignored by IPv6 interfaces.
| Top |
Specifies whether to allow suppression of hello packets. This support is only used for point-to-point-interface and point-to-multipoint interfaces types that are on demand circuits. This parameter only applies to IPv4.
| Top |
Specifies the interval time that OMPROUTED will try to re-establish a relationship with a neighboring router that has failed but the interface is still active. This parameter is used only if the interface is Point-to-Point type and suppression for hello has been enabled. This parameter is ignored for OSPF IPv6 interfaces.
| Top |
Specifies if the router is connected to a non-broadcast or multi-access (NBMA) network.
| Top |
Specifies the time interval for hello packets to be sent from this interface to neighbors that are inactive. It is only valid if *YES is specified for the Nonbroadcast link (NBCLNK) parameter.
| Top |
Specifies the list of routers eligible to be treated as neighbors for this system over this interface.
Up to 10 neighboring routers can be defined.
Note: It is not necessary or recommended to define neighbors on nonbroadcast or multicast-capable media. If you do define neighbors on these media, OMPROUTED will be able to communicate OSPF information only with those neighbors that are defined (it will not form adjacencies with any additional neighbors).
Element 1: Internet address
Specifies the neighboring router's internet address.
Element 2: Authentication key identifier
Specifies whether or not the neighbor router may be eligible to be a designated router.
| Top |
Specifies the IPv6 protocol instance number for this interface. This value should be the same as the instance value of other IPv6 OSPF hosts or routers that OMPROUTED communicates with on the link. This value will be set in all the outgoing IPv6 OSPF packets. All the incoming OSPF packets whose instance value does not match with the instance value set for this interface will be ignored. This characteristic permits multiples instance of IPv6 OSPF to be run on this link. OMPROUTED supports only one instance per link, however if this parameter is configured in order to interact with router that can supports multiples IPv6 OSPF instances on a link.

Example 1:Adding an OSPF IPv4 Interface
ADDOSPFIFC IFC('9.67.107.7')
This command adds an OSPF IPv4 interface. The referenced logical interface must exist on the system.
Example 2:Adding an OSPF IPv6 Interface
ADDOSPFIFC IFC('1000::5678:9abc:def')
This command adds an OSPF IPv6 interface. The referenced logical interface must exist on the system.
Example 3:Adding an Interface that Will Work Over a Point-to-Point Link
ADDOSPFIFC IFC(*PPPCNNPRF) PPPCNNPRF(PROFILE1)
This command adds an OSPF IPv4 interface using a connection profile. The connection profile PROFILE1 must have already been configured using Remote Access Services.
