14. In the Authentication ID field, enter the ID that must be used for authentication on
the interface.
If you select Encrypt from the Authentication Type menu, you must set an ID, which
is a number between 0 and 255.
15. Click the Add button.
Your settings are saved.

The following table describes the view-only fields on the page.
Description Field
Neighbor State
The state of the OSPF neighbor interface
Down: This is the initial interface state. The interface is not usable for OSPF, and the interface settings are at
their initial values. All interface timers are disabled, and no adjacencies are associated with the interface.
Loopback: The interface is looped back either in hardware or software. The interface is unavailable for regular
data traffic. You can get information about the interface by sending ICMP pings to the interface or through a
bit error test because IP packets can still be addressed to an interface in a loopback state. An interface in a
loopback state is advertised in LSAs as single host route for which the destination is the IP interface address.
Waiting: The neighboring device is monitoring received hello packets to detect the identity of the backup
designated router for the network. The neighboring device cannot elect a backup designated router or a
designated router until it transitions out of the waiting state. This prevents unnecessary changes of the backup
designated router.
Designated Router: The neighboring device is the designated router on the attached network. Adjacencies
are established to all other routers and switches that in the network. The neighboring device must also originate
a network LSA for the network node. The network LSA contains links to all switches and routers (including the
designated router) in the network.
Backup Designated Router: The neighboring device is the backup designated router on the attached network.
The neighboring device is promoted to designated router if the current designated router fails. The neighboring
device establishes adjacencies to all other routers attached to the network. The backup designated router
performs slightly different functions during the LSA flooding, as compared to the designated router.
Other Designated Router: The interface is connected to a broadcast on which other routers are the designated
router and backup designated router. The neighboring device attempts to form adjacencies to both the
designated router and the backup designated router.
State
The state of the OSPF switch interface:
Down: This is the initial interface state. The interface is not usable for OSPF, and the interface settings are at
their initial values. All interface timers are disabled, and no adjacencies are associated with the interface.
Loopback: The interface is looped back either in hardware or software. The interface is unavailable for regular
data traffic. You can get information about the interface by sending ICMP pings to the interface or through a
bit error test because IP packets can still be addressed to an interface in a loopback state. An interface in a
loopback state is advertised in LSAs as single host route for which the destination is the IP interface address.
